6Historical Background
7Historical BackgroundLocation
- Roman architecture refers to the architecture of
Rome and of the Roman Empire - The Roman Empire was one of the largest early
empires in history, stretching from England in
Northern Europe to the Ancient Near East and
Africa - The pink area of the Map shows the greatest
extent of the Roman Empire - Rome, located on the Italian peninsula was the
capital of the empire - From the capital, an infrastructure of roads and
communication systems was established to connect
the whole empire - Rome is today the capital of Italy
8Historical BackgroundPeriod
- The city of Rome was founded in 753 BC.
- Roman civilization with Rome as capital lasted
for more than a thousand years. - The history of the civilization can be divided
into three periods - 753- 510 BC Etruscan Period
- 510 44 BC Republican Period
- 44 BC 476 A.D. Imperial Period
9Historical Background Period- Etruscan Period
- Romans fix the date of the founding Rome at 753
B. C. - Prior to this date, the Etruscans established an
urban culture in the Italian peninsula, which
reached the height of its development around 600
B.C. - They had conquered and established their
authority over a loose federation of cities - Rome at its foundation was a minor city and
became a colony of the Etruscans
10Historical Background Period- Etruscan Period
- Rome was ruled by Etruscan Kings aided by a
popular assembly - Towards the end of the 6th century B.C., Etruscan
power began to decline - In 509 B.C. Rome revolted against their king and
established an independent city state - Further decline in the power of the Etruscans was
accompanied by the rising influence and
increasing significance of Rome
11Historical Background Period Republican Period
- After the expulsion of its Etruscan Kings, Rome
gradually assumed leadership of a number of
settlements for mutual defense - This gradually led to the expanding influence and
dominance of Rome - By 273 B. C. Rome became the established dominant
force in the region - It conquered its rivals, defeating Cathage in 146
B.C., Macedonia in 168 B. C., Greece in 146 B.C.,
and Syria in 64 B. C. - With time Rome also developed a system of
Representative government
12Historical Background Period Republican Period
- Rome was government by a body of elected male
representatives of the population known as the
Senate - This is why the period is referred to as
republican or in other word democratic - Towards the end of the last millennium B.C. Rome
entered into a series of civil wars which brought
about the rise of some military dictators, of
which Julius Caesar was the most successful. - This brought about the end of the republican
period
13Historical Background Period Imperial Period
- Following a series of civil wars that ended in 27
B.C. Caius Ocatavius, who later took the name
Caesar Augustus assumed the title of emperor - This ushered in the Imperial period of Roman
history - Emperor Augustus undertook a significant
reorganization of the Roman Empire - The golden age of architectural development was
witnessed during this period - He revitalized national life and created new
building works
14Historical Background Period Imperial Period
- Augustus was credited with saying that he met
Rome a city of brick and left it a city of marble - Later it was to transform to a city of concrete
- The 3rd century A.D. was a period of political
confusion in the Roman Empire - The Barbarian people living in the north of
Europe started attacking the Empire - In 286 A.D. Roman Empire was split into two a
western empire and an Eastern empire
15Historical Background Period Imperial Period
- Emperor Constantine was able to reunite the
Empire again in 324 A.D. and established a new
capital for the empire at the city of Byzantium,
which he renamed Constantinople - After his death, the Empire was split again and
each had a different destiny - In 476 A.D. the western empire with its capital
at Rome fell after century of attacks by Vandals
and Visigoths ending the history of that part - The Eastern Empire with its capital at
Constantinople survived and became the focus of a
civilization that lasted until 1453 A.D. when it
was sacked by the Ottoman Turks
16Historical Background Social Characteristics
Beliefs
- Introduction
- The Roman Empire consisted of Rome and all its
conquered provinces - Rome was the capital and focus of the Roman
Civilization - Roman society was made of the Latinized people
living on the Italian peninsula and other foreign
people belonging to the conquered provinces - The society was not homogenous as its puts
together people of different origins - Latin was the widely spoken language,
particularly in Rome and its environment - The Roman people were classified into citizens
and non citizens citizenship can be conferred on
non citizens
17Historical Background Social Characteristics
Beliefs
- Introduction
- Citizenship confers the right to vote, make
contracts and have a legal marriage - Citizens are divided into two classes members of
the Roman Senate belonging to the highest social
class and other citizens - The Roman people were essentially farmers and
traders - Many also aspired to became solders and warriors
being a warrior provided one of the best means of
advancing in the society
18Historical Background Social Characteristics
Beliefs
- Social Life
- Roman society had an active social life
- The forum was the center of social life it is
very similar to the Greek Agora - The forum was the place for social, political,
recreational and religious activities - Romans participated in a lot of entertainment
activities
19Historical Background Social Characteristics
Beliefs
- Social Life
- These activities include spectator sports such as
drama, chariot racing, and gladiatorial contest - They also had new unique social activities such
as recreational bathing - The practice saw Romans going to a public bath at
luxurious bathing through chambers of different
temperature - In the process they engaged in both intellectual
and physical interaction
20Historical Background Social Characteristics
Beliefs
- Religious Beliefs
- Roman people were not deeply religious,
particularly during the early part of their
development - They did not have religious beliefs and
mythologies of their own, but borrowed from
societies they come into contact with. - Contact with other people always resulted in
changes to their culture, art and way of life - Most of their religious beliefs were borrowed
from the Greeks, and like the Greeks, they also
believed in a number of Gods
21Historical Background Social Characteristics
Beliefs
- Religious Beliefs
- The Romans believed that the faith of their
empire lies in the hands of their various Gods - The state spent money to built temples to the
various gods - Public assemblies, such as senate meetings, war
victories and most state functions were always
started with sacrifices to a particular god in
his temple - The religious well being of the individual Roman
was his own concern
22Historical Background Social Characteristics
Beliefs
- System of Government
- The System of government in ancient Rome was
democratic - During the Republican period, Government
consisted of two elected consuls, a senate and
judiciary - The consuls acted as the executive arm of
government overseeing the activities of the
senate, army and other executive institutions
such as tax collectors and police - The senate was an assembly of selected land
owners, the upper class of Roman society, who
approve budgets and suggest laws
23Historical Background Social Characteristics
Beliefs
- System of Government
- Members of the senate are elected from a series
of lower assemblies who are responsible for
enacting the laws suggesting by the senate and
also implementing them - The judicial branch consist of 6 judges who were
elected every two years, who decide punishment
for criminals - During the imperial period, the Consuls were
replaced by Emperors who wielded a lot of power
24Historical Background Social Characteristics
Beliefs
- Roman Architecture
- The Environment around Rome was not as rich as
the Greek mainland in construction material
especially marble - Romans construction material consists of Stone,
principally local travertine and timber - Roman also invented a system of firing brick and
used brick widely in construction - Romans were also the first people to discover
concrete Roman concrete is different from our
present day concrete - Romans made significant improvements to the arch
to address its shortcoming
25Historical Background Social Characteristics
Beliefs
- Roman Architecture
- They also developed new construction systems
based on the arch and dome - The combination of arch and vault construction
with brick as formwork and concrete as bonding
material enabled the Romans to construct great
buildings with very large interior spaces - Roman construction also developed the system of
wooden truss construction - The architecture of Rome has its origin in
Hellenistic Greek Architecture and the
architecture of the Etruscans - Most Roman architects were either of Greek origin
or Greek trained
26Historical Background Social Characteristics
Beliefs
- Roman Architecture
- The Romans adopted the external language of
classical Greek architecture - In Roman architecture, the orders survived simply
as ornaments applied to great concrete buildings.
- But the Romans also made unique additions to the
orders that are very important. - New orders evolved and were added to the Greek
orders to form the classical language of
architecture - Romans also made additions in the entablature of
temples, in the scale of buildings and the
proportion of the entire design. - While the Greeks are said to be the inventors of
form, Roman architecture concentrated on the
creation of space
27Historical Background Social Characteristics
Beliefs
- Roman Architecture
- The Greek and Roman architecture are referred to
as classical architecture - The first book on architecture was produced by
Marcus Vitruvius Pollio in 100 A.D. - The ten books of architecture written sets down
rules and procedures for creating architecture of
value - The genius of Roman architecture was expressed
not in the design of a particular building, but
in the production of a vast number of various
building types - Roman buildings include bathhouses for bathing,
circuses for racing, amphitheatres for
gladiatorial contest, temples for religion, domus
for family life and the forum as the center of
public life and national commerce
28Historical Background Social Characteristics
Beliefs
- Other Achievements
- Other contributions of the Romans include the
Roman alphabets which is widely used in Western
and Central European languages and the Roman
numerals - The Roman also introduced the calendar which even
thought it has changed several times before
assuming its current form has endured to the
present day - The influence of the Roman Empire's is visible in
the government, law, and monumental architecture,
as well as many other aspects of Western life - The various contributions of the Roman
civilization to modern life has resulted in its
classification along with the Greek civilization
as Classical civilizations

32Architecture of the Civilization
33Roman Architecture Early Influences- The
Etruscans
- The Earliest civilization in the region around
Rome were the Etruscans - The Etruscan civilization existed in the northern
part of what is now Italy, prior to the formation
of the Roman Republic. - During the 700s BC, the Etruscans developed into
a series of autonomous city-states Rome was a
part of these city states - Knowledge about the Etruscans is fragmentary, and
usually filtered through Roman eyes - The Etruscans created the first visible
civilization in Italy. - They brought sophisticated Eastern and Greek
culture to the region.
34Roman Architecture Early Influences- The
Etruscans
- Not much has survived of Etruscan buildings to
the present however. - The temple shown in the image is a reconstruction
of a typical Etruscan temple - The Etruscans introduced another order of
architecture - This order, known as the Tuscan order became
popular with the Romans
35Roman Architecture Early Influences- The
Etruscans
- The Tuscan order had a simpler base and the shaft
was without flutes - The capital and entablature were also without
decoration - In proportion it is similar to the Doric order
with a column that is seven diameters high - Compared with the other orders, the Tuscan order
looks the most solid
36Engineering Achievement Introduction
- Romans created what can be referred to as a
structural revolution - This revolution centers on their understanding
and use of the arch and vault - They also discovered the groin vault
- Because of this structural revolution, they were
able to span large openings in buildings and
other structures with economy and strength - They were also able to design and construct
buildings with large interior spaces - The revolution also allowed the Romans to
construct large engineering structures such as
bridges to connect all parts of their empire, and
aqueduct to supply water to their cities
37Engineering Achievement Structural Innovation-
Arches
- The arch was not a new building form, as it had
been known by other civilizations including the
Egyptians and the Greeks - But the Romans used it to its fullest potential
- The arch is an organic structure with the
elements of the arch resting on each other and
transferring load to the column - It was particularly useful over doors and openings
38Engineering Achievement Structural Innovation-
Arches
- With an arch, there are no tensile stresses as
all the forces are in compression and building
stone has enormous compressive strength - Up to a certain point also, the more an arch is
loaded the stronger it becomes - Arches were used over doors and openings and
sometimes, they are built over a lintel to
deflect the load to the surrounding walls.
39Engineering Achievement Vaults
- Vaults are used to cover an area as a roof
- The simplest of the vaults is the Barrel vault,
which is just made up of an arch extended over a
certain distance - It can be adapted to suit different types of
plans by making simple modifications to it - The disadvantage of the vault is that it exerts a
continuous load and therefore needs some form of
continuous support - It is also difficult to light the space under a
vault except from the ends - The Romans invented unique ways of overcoming
these difficulties
40Engineering Achievement Vaults
- The cross vault was created from the barrel vault
to overcome some of the problems of the ordinary
vault - This is formed by intersecting two barrel-vaults
at right angle and is called a groin vault - The weight of the groin vault is concentrated at
the corners eliminating the need for continuous
support - The opening of the space in 4 directions means
that ample light can be provided to the area
below it
41Engineering Achievement Vaults
- The image shows an example of the use of arches,
vaults and groin vaults in a Roman building - The major limitation of the groin vault is that
it is limited to a square plan - The dome was another structure that was used in
roman architecture. - The Romans used the true dome with its fully
rounded perfection
42Engineering Achievement Concrete
- The Romans were the first to develop concrete
- The concrete developed by the Romans is different
from modern concrete and is made up of lime, sand
and water - Around the 2nd century BC, Pozzolana or volcanic
ash was also added - Concrete did away with the need for stone
quarries - It also did away with the need for the shaping
and transportation of stone and for high skilled
labor for stonemasonry
43Engineering Achievement Concrete
- Concrete has the advantage that it can be cast in
any shape and in far larger sizes than the
megalithic blocks of stone used in buildings - With concrete, it was possible to construct
monolithic vaults and arches - Concrete buildings were normally faced with other
materials to hide the ugly look of the concrete. - Fired brick used as formwork was the most popular
covering material
44Engineering Structures Introduction
- The structural revolution introduced by the
Romans enabled them to introduce a variety of new
civil structures and building programs never seen
before their time - The ability of the Romans to create large
structures enabled them to build significant
civil structures including aqueducts, bridges and
sewers - The Romans lived principally in cities and
generally cities need a steady supply of fresh
water - Rome itself was projected to have a population of
more than a million at the peak of its power
45Engineering Structures Introduction
- Arcuated structures or Structures built with
arches played a major role in bringing this water
to the city - The technique of arcuated construction was also
applied to the construction of bridges - Rome also had a sanitary system to take away
waste water from the city and large warehouses to
service the needs of its port
46Engineering Structures Road and Bridges
- The Trojans Bridge Alexandria is an example of
ancient Roman structural achievement - It is also amongst the most impressive of the
surviving Roman bridges - The bridge consist of tall piers and wide
spanning arches - The central arches are slightly above 27 meters
in length - The roadway is carried 48 meters above the River
- A commemorative arch stands at the center of the
Bridge the commemorative arch bears the name of
the architect of the bridge
47Engineering Structures Aqueducts
- Aqueducts were used to supply water to Roman
cities - The Pont Du Gard is probably the most magnificent
of the Roman aqueducts - It was constructed around 50 A.D. to supply water
to the city of Nimes - The Aqueduct in some places is almost 50 meters
above the deep valley of the River Gard
48Engineering Structures Aqueducts
- It was constructed of 3 tiers of arches
49Engineering Structures Aqueducts
- The Aqua Claudia is also another example of Roman
aqueduct - The Aqua Claudia was one of the eleven aqueducts
that supplied Rome with water - The aqueduct supplies water to Rome over a
distance of 66 kilometers
50Roman Buildings Introduction
- The focus of Roman building design was on
functional spaces - The Roman people demanded buildings of various
functions from the Roman architect - The architects were able to respond, creating
buildings that answer to their functional
requirement by providing appropriate interior
spaces - The buildings types include theaters,
amphitheaters, basilicas, circuses, basilicas,
temples and baths - All of these buildings were erected within the
dense fabric of the city - We will examine each of these building types
51Roman Buildings Theaters
- The Romans adopted the Greek theater transforming
it into something Roman - There was an expansion of the stage and the whole
theater was contained within a high-unbroken wall - The Greek Theater was blended into the landscape
- In contrast, the Roman Theater was an urban form
located in a flat city - The structure of the theater consists of massive
structural arcades on piers
52Roman Buildings Theaters
- A purely cosmetic layer of trabeation was added
to the front - The trabeation was of the Greek orders and gave
scale to the building - It also creates a rhythm of solids and voids on
the elevation - The three orders of Greek architecture were used
on the theater elevation - Theaters were built in every Roman City
53Roman Buildings Theaters
- The Theater was used for acting and drama
- The Theater Marcellus constructed between 23 to
13 B.C. was the first theater constructed in the
capital Rome - It is a good example of a Roman theater
- Access to its banked seat is from the rear,
providing access circumferentially - A stage runs from end to end in front
- The stage is enclosed by a tall wall
54Roman Buildings Amphitheater-Introduction
- The amphitheater is a roman structure with no
Greek equivalent - Amphitheatre is a public building used for
spectator sports, games and displays - Apart from function, the important outward
distinction between an amphitheatre and a theatre
is that amphitheatre is round or oval in shape - An amphitheater was first built in Pompeii in 80
BC, but the best example of the Roman
amphitheater is the colosseum
55Amphitheater Coliseum, Rome
- The Colosseum is an amphitheater in Rome
- Its construction began under the Emperor
Vespasian in 72 A.D. and was completed in A. D.
80 - It was used for spectator sports including
gladiatorial combat - It is said that 9,000 wild animals were killed in
the one hundred inaugural days celebrating its
opening - The Colosseum hosted large-scale spectacular
games that included fights between animals, the
killing of prisoners by animals and other
executions, naval battles via flooding the arena,
and combats between gladiators
56Amphitheater Coliseum, Rome
- It has been estimated that about 500,000 people
died in the Colosseum games - The colosseum is elliptical in shape
- It measured 48 metres high, 188 metres long, and
156 metres wide - The wooden arena floor was 86 metres by 54
metres, and covered by sand - The colosseum had a seating capacity for 50,000
spectators
57Amphitheater Coliseum, Rome
- The Colosseum was ingeniously designed most
spectacle venues have been influenced by the
Colosseum's structure into modern times - The seating formed a uniform elliptical ring
capable of supporting the 50,000 spectator
capacity of the facility - The substructure of the amphitheater is very much
like that of the theater - Vaulting was used both radially and
concentrically to support the structure
58Amphitheater Coliseum, Rome
- The Colosseum also had a passageway that opens
into a tier of seats from below or behind - Each entrance and exit was numbered, as was each
staircase - The passages quickly dispersed people into their
seats and upon conclusion of the event disgorged
them with abruptness into the surrounding streets - Seating was divided into different sections
- Above the podium was the maenianum primum, for
the other Roman aristocrats who were not in the
senate - The third level, the maenianum secundum, was
divided into three sections - The lower part, the was for wealthy citizens,
while the upper part was for poor citizens - A third, wooden section was a wooden structure at
the very top of the building, added by Domitian
59Amphitheater Coliseum, Rome
- The most ingenious part of the Colosseum was its
cooling system - It was roofed using a canvas covered net-like
structure made of ropes, with a hole in the
center - The Arena where the action takes place is located
at the center of the ellipse - Underneath the arena was the "underground", a
network of tunnels and cages where gladiators and
animals were held before contests began
60Amphitheater Coliseum, Rome
- The arena floor no longer exists, and the
hypogeum walls and corridors are clearly visible
in the ruins of the building - The orders were used in the elevation in the same
manner as on the theater - The Colosseum was in continuous use until 217,
when it was damaged by fire from lightning - It was restored in 238 and gladiatorial games
continued until Christianity gradually put an end
to some sports

- Residential Buildings
- Other Elements
- Triumphal Arches
64Roman Buildings Circuses
- The Romans developed circuses or stadium for
horse and chariot racing - Every city usually had one located close to the
forum - The circuses had stalls at one end where the
chariots emerge at the beginning of the race and
a track which they race around - The structure of the circus is very similar to
that of theaters and amphitheaters - Circus Maxima is an example of a Roman Circus
65Circuses Circuse Maxentius
- It is located in Rome and is one of the oldest
- It went through a series of transformation over
the period of its existence - The image shown is its final form around 400 A.D.
- Its is 600 meters in length by 200 meters in
width - The circus had 3 tiers of seat, and there are
stalls for 12 race houses or chariots - Each race was of 7 laps covering a distance of
about 3.6 kilometers
66Roman Buildings Bath
- The Romans had a unique need for exercise,
bathing and relaxation and they devised a unique
architectural element, the Bath to address that
need - The roman bath was more that just merely swimming
or washing - This practice became so popular that at some
point, they took it more serious than their gods - It was a daily practice of almost all Romans to
go to a Bath once a day to relieve stress
67Roman Buildings Bath
- The bathing procedure involves a pattern of
exposing the body to various levels of heater air
and water - The core program of the bath consist of a
disrobing room, the apodyterium, a series of at
least two heated rooms, the tepidarium, and a hot
room or cauldarium - Besides the heated rooms, the bath may also have
a swimming pool, or natatio for cold plunges on
hot summer days or a cool unheated room called
the frigidarium - Bathing also dries the skin so baths also
provided rooms with special attendants to oil and
towel bathers dry - Wealthy people and Emperors had private both, but
the greatest baths were the public ones built for
the populace
68Roman Bath Bath of Caracalla
- The bath of caracalla is a good example of a
Roman bath and among the best preserved - The bath is set free standing within a square
precinct enclosed by walls - The precinct has a water reservoir to the south,
supplied by an aqueduct to service its water need
69Roman Bath Bath of Caracalla
- The reservoir is located beneath a stadium used
for athletic contest - The east and west walls have a curved exedra that
defines space for cultural activities such as
library, music performance, philosophical
lectures, etc - The front wall has a series of shops with the
entrance at the center
70Roman Bath Bath of Caracalla
- The main bath building is rectangular, 225 meters
by 115 meters and is situated within the walled
precinct - It has a perfect bilateral symmetry along its
north-south axis - The bath has a large dressing hall, apodyterium
at the center of the building
71Roman Bath Bath of Caracalla
- A swimming pool or Notato is located to the north
of it, while a tepidarium and a domed circular
cauldarium is located to the south of it, where
it is more sunny - A series of supplementary rooms, including
Gymnasium and bathroom suits are arranged
symmetrically on two sides of the building - The structure of the bath of carracalla is made
up of vaults, arches, groin vaults and domes - The interior also shows how the Romans have been
able to adapt the Greek orders and treatment to
arch and vault construction
72Roman Buildings Temples
- Temples were a significant part of roman
architecture - Scores of temple were built during every period
- Most of the roman temples were combination of
Etruscan and Greek prototypes - The typical temple had an axial plan, an entrance
porch with widely space columns in front - The temple also had a cella or sanctuary
- The whole temple is raised on a high podium with
frontal steps providing access - A good example of the early form of the temple is
seen in Maison Carree in Nimes - The best preserved of the temples and the one
showing the highest achievement in temple
architecture is the Pantheon
73Roman Temples Maison Caree, Nimes
- Maison Carree is located in Nimes France
- It was built by the Emperor Agrippa
- The temple shows Greek influence on early roman
temples - The temple is 26.5 meters long, 15.5 meters wide
and raised on a podium 3.3 meters high - It is a temple with 6 Corinthian columns in
front, 10 diameters high
74Roman Temples Maison Caree, Nimes
- Its podium is three and half times the height of
the entablature with 15 access steps in front - It has an entrance porch that is 3 columns deep
- The temple has a cella that is one and half times
long as its wide
75Roman Temples Maison Caree, Nimes
- The walls of the cella have attached half
Corinthian columns on its visible three sides
76Roman Temples Pantheon
- The Pantheon is the best surviving of all
classical buildings - It is also represents the highest achievement of
Roman architecture - It was built between AD 118 and 128 by the
Emperor Handrian on the site of an earlier temple
by Agrippa - It was built as a temple dedicated to all the
Roman Gods, hence the name Pantheon
77Roman Temples Pantheon
- The Pantheon essentially consist of two parts
the an entrance portico and a circular part or
rotunda - The portico is 8 columns wide and 3 columns deep
and leads to the entrance of the temple - The columns are of unfluted Corinthian order
- The wall of the rotunda is 3 storeys high on the
outside they are made up of brick faced concrete
and support the dome roof of the temple
78Roman Temples Pantheon
- The interior has eight large niches with one
serving as the entrance and the remaining seven
used dedicated to the seven major Roman Gods - The Dome roof forms a perfect sphere with a
diameter of 142 feet in the interior
79Roman Temples Pantheon
- At the head of the dome is a 30ft wide occulus,
that opens up the great dome to the outside and
illuminates the space with light - The interior was built of Egyptian granites,
African colored marbles and pure white marbles
from the Aegean - The Pantheon combines scale, boldness and mastery
of every architectural art.
80Roman Buildings Basilica
- Basilicas are among the most important categories
of roman architecture - There were no basilicas before the Roman era
- The basilica are rectangular and usually
contained interior colonnades that divided the
space into aisles at one or both sides, with an
apse at one end - The central aisle tended to be wide and was
higher than the flanking aisles, so that light
could penetrate through the clerestory windows - The function of the basilica is close to that of
the Greek stoa
81Roman Buildings Basilica
- It is also the place where magistrates to hold
court to dispose of legal matters - The oldest known basilica, the Basilica Porcia,
was built in Rome in 184 BC - The most splendid Roman basilica is the one
constructed for traditional purposes during the
reign of the pagan emperor Maxentius and finished
by Constantine after 313 - In the early Imperial period, a basilica for
large audiences also became a feature of the
palaces - We will examine the Basilica Ulpia and the
Basilica Maxentius
82Roman Buildings Basilica Ulpia
- The Basilica Ulpia was built by Emperor Trajan in
the period A.D 98-117 for his imperial forum - Basilica Ulpia stretches for 120 meters in length
over the width of the Trajan forum - The Basilica consists of a central hall, 25
meters wide surrounded on all sides by double
colonnades - The Basilica had two semi-circular apses at its
two ends
83Roman Buildings Basilica Ulpia
- The walls of the Basilica were finished with
multi-colored marble also referred to as
polychromatic marble - The whole structure was covered with a truss roof
- Basilica Ulpia represent the generic form of the
Roman Basilica, - It is this form that will later be adopted by the
Christians for their church
84Roman Buildings Basilica Maxentius
- The Basilica Maxentius was started by the Emperor
Maxentius in A.D. 308 but was completed by the
Emperor Constantine in A.D. 312 - It is also sometimes referred to as Basilica of
Constantine - It is one of the impressive buildings of the
Forum Romanum - The Basilica Maxentius is different from other
tradition basilicas, because its design was
derived from the central halls of imperial Roman
Baths
85Roman Buildings Basilica Maxentius
- It is however larger in scale than any of the
baths that was built - The ground plan covers 100 meters by 65 meters
- The building is divided into a central nave and
side isles - The central nave was 80 by 25 meters and was
covered by 3 groin vaults with a maximum height
of 35 meters - The side isles were 16 meters wide, divided into
three sections - There is very little that is left of the Basilica
now
86Roman Buildings Residential Buildings
- Roman cities had a range of various types of
private dwellings - The private dwellings reflected the rank and
wealth of the inhabitants - At the lowest level are the multi-story tenements
where a large proportion of the population stayed - They consisted of shops on the ground floor and
apartments on the upper floors - The apartments were built around a courtyard for
light and air
87Roman Buildings Residential Buildings
- The common roman house was the domus
- These were reserved for the more well off members
of the Roman society - The domus was essentially a courtyard house, with
a peristyle colonnaded courtyard - It had few or no windows to the outside
88Residential Buildings Domus Augustana
- At the high end are elaborate palaces and villas
for the very rich - The Domus Augustana, also called flavians
palace, is an example of the high-end residential
palaces - Domus Augustana was both a house for the emperor
as well as his palace for official functions
89Residential Buildings Domus Augustana
- It was laid out around two peristyle atriums
- The atrium to the left is for state function
- Entry is from an inconspicuous door from the top
- The residential part of the palace is arranged
around the courtyard located to the right - To the right of the residential part is a sunken
garden in the form of a stadium - This is the private garden of the emperor, where
he can interact with nature
90Residential Buildings Handrians Villa
- Romans also built country villas or houses, where
they could go to be close to nature - A very good example of the country villas, is the
Handrians villa built for the Emperor Handrian - The Handrian villa displays an example of the
level of wealth displayed in buildings - This was a large country estate spread on a vast
terrain
91Residential Buildings Handrians Villa
- The structure was made of a loose arrangement of
peristyle halls, fountains, dining halls,
dormitories, baths, libraries and other
facilities - The most characteristics feature of the villa is
the play of curves and curved form - This is most evident in the Canopus
- This is an elongated pool surrounded by a
colonnade - The colonnade is topped by alternating straight
entablature and segmental arch sections framing
statuary
92Other Architectural Elements Triumphal Arches
- Other Than buildings, ancient Romans also
contributed to the development of several
architectural elements - The most prominent of the elements is the
triumphal arch - A triumphal arch is a structure in the shape of a
monumental gate, usually built to celebrate a
victory in war - They are almost always built in the Form, framing
the paths that people follow - Romans started it as a way to celebrate their
victories in battles
93Other Architectural Elements Triumphal Arches
- Some triumphal arches are made of stone and
intended to be permanent. - A number of arches from the city's imperial era
can still be seen in modern Rome. - Temporary triumphal arches were also constructed
for use for celebratory parades or ceremony and
later dismantled - A Roman Triumph was a civil ceremony and
religious rite held to publicly honour the
military commander of a notably successful
foreign war - Only men of senatorial or consular rank could
perform a triumph celebration and be a
triumphator as the victorious generals are known
94Other Architectural Elements Triumphal Arches
- The ceremony consisted of a spectacular parade,
opened by the chiefs of conquered peoples who are
afterward executed - The triumphator rode on a biga, a chariot pulled
by two white horses - The parade followed a precise route in the
streets of Rome - It traveled along the Forum until it reached the
Temple of Jupiter Optimus Maximus, where the
laurels of victory were offered to the god. - Monuments may then be erected to celebrate the
triumph - Two examples of such monuments in the republican
forum are the Arch of Titus and the Arch of
Constantine
95Triumphal Arches Arch of Constantine
- The arch was built in A.D. 81 and dedicated to
the emperor Titus - It was built to commemorate the military victory
over Jerusalem in A.D. 70 - The arch has a height of 15.4 meters, a width of
13.5 meters and was constructed of stone - The marvel of its stone construction is evident
in the keystone, which ensures the stability of
the arch
96Triumphal Arches Arch of Constantine
- It has a single opening flanked on each side by
attached columns of the Composite order - The composite order has a capital that joins the
acanthus leaves of the Corinthian order with the
volutes of the ionic order - The face of the arch is decorated with sculptural
relief depicting the destruction of the temple in
Jerusalem
97Triumphal Arches Arch of Constantine
- The arch of Constantine was built much later that
than of Titus - It was built to commemorate the victory of
Emperor Constantine over Maxentius in A.D. 312 - Its form shows an attempt to create an arch more
majestic than that of Titus
98Triumphal Arches Arch of Constantine
- It has three arched openings, a larger one in the
center flanked by two smaller ones - There are four free standing columns in front
framing the arched openings - It is also abundantly decorated, depicting the
victory in relief sculpture

- Lecture 25
- Roman City Planning and Design
- Architectural Characteristics
- Buildings and other architectural elements
- Building materials, construction and technologies
- Architectural Organizing principles
102Roman City Planning Design Principles
- Roman cities fall into two broad categories
- Majority grew in an unplanned manner over the
centuries forming complex organic entities, to
which sometimes order was introduced - Rome is a good example
103Roman City Planning Design Principles
- The other category consist of Castrum type
cities, a type of military camp developed with an
inflexible regularity of shape- - A well preserved example is the city of Timgad in
North Africa - This was a city laid out by Trajan in A.D. 100 as
a colony for military veterans - The town was laid in a grid of 12 blocks within a
square 1,200 feet wide
104Roman City Planning Design Principles
- The planning of most cities fall in between the
two extremes of organic growth and rigid grid
planning - All cities had a forum, theater, bath, market
etc. - Many of the cities contained buildings that were
copies or local versions of key monuments in Rome - Focus in city design is on integrating civic
buildings with public spaces and residential
neighborhoods - Each public building had interior spaces that
responded to functional requirement with the
spaces also linked and connected with the public
spaces of the city - The Forum was the center of the Roman city
105Roman City Planning Design Forum
- The forum was the descendant of the Greek agora
for the Romans - It began as a market place
- It rapidly became the commercial, political and
ceremonial center of the civilization - In the process it developed into an elaborate
architectural space that became a part of all
roman cities - Unlike the Greek agora which is informal in plan,
and whose buildings are subordinate to the space,
in the roman forum, the organization is more
formal - The buildings surrounding it are normally large
and dominate the space - Buildings commonly found in the forum include
temples, basilicas, and bath
106Roman City Planning Design Forum
- Each individual major building in the forum was
given a central inside space - Governmental function were usually arranged on
the West End religious ceremonies were
celebrated at the east end - The inside space of buildings was connected to
one or more exterior space of the city - Columns, statues and triumphal arches were
erected as a memorial to the conquering rulers
and to the glories of the empire - No two roman forums are really alike, as there
are always differences between the forums in
different cities - In Rome with its two forums, we find a good
example of the Roman forums
107Roman City Planning Design Republiclan Forum
- The Republican Forum is also called the Forum
Romanum - It was the oldest and most important forum in the
city - Soon it became an important market place
- By the 5th Century B.C. the various functions
associated with the forum began to assume their
architectural shape
108Roman City Planning Design Republican Forum
- Additions, modification and growth by successive
republicans and emperors led to its development - By 400 A.D. the forum had accumulated not less
than 10 temples, 4 basilicas, 4 triumphal arches
and many other monuments and shrines - All of these were arranged with no preordained
order - The buildings therefore loosely define the space
of the forum
109Roman City Planning Design Imperial Forum
- During the reign of Julius Ceasar, he attempted
to reorganize the Republican forum but realized
that it had become too congested for rational
order - He therefore decided to build a new forum
adjacent to but outside the republican forum - This idea was picked by successive emperors, who
added to it to create the imperial forum
110Roman City Planning Design Imperial Forum
- The imperial forum is not one forum, but five
forums with each supporting the other - There was variety in their form, but they
displayed rational order in their organization - Each of the forum consisted of colonnaded atrium
with a temple at its head - Of the five temples that of Trojan was most
majestic, with the basilica Ulpia sitting across
it and two libraries on either side of the
central court
111Roman City Planning Design Architecture and
Urban Design in Rome
- In Rome we find the best example of both Roman
architecture and city design - The image shows a reconstruction module of a part
of Rome at the height of its development - From the image, the organic growth of the city is
evident and is reflected in the fabric of the
city - Buildings are densely packed together, separated
by a network of narrow pathways
112Roman City Planning Design Architecture and
Urban Design in Rome
- Within the fabric, all the Roman building types
can be identified - These include The circus Maxentius, The Domus
Augustana, Roman Theater, An Aqueduct, A Roman
Temple, The Basilica Maxentius, and The
Republican and Imperial Forums - From the image, the clustering of important
buildings close to the forum is highly evident
113Architectural Characteristics
114Buildings Other Arch Elements
115Buildings Other Arch. Elements Building Types
- The genius of the roman architect was not in the
design of a particular building - Rather, it is in the way they were able to meet
the needs of a complex society for different
building types for a thousand years - They produced a wide range of buildings that had
never been built before - Roman buildings included bathhouses for bathing,
circuses for races, amphitheaters for
gladiatorial contest, temples for religion, domus
for family life and the forum as the center of
public life - Roman architects design the buildings with
interior spaces configured for specialized
activities - The Greek order was reduced to a decorative
element rather than as a form generator in Greek
Architecture
116Buildings Other Arch. Elements Engineering
Structures
- Romans also contributed several engineering and
architectural objects to human civilization - The most prominent engineering contributions are
in road and bridge structures and in the
construction of aqueducts - Road and bridge construction allowed the Romans
to connect the various parts of their empire - Aqueducts allowed them to supply their cities
with water
117Buildings Other Arch. Elements The Orders
- Romans also contributed to the development of the
orders - They made the Tuscan order developed by the
Etruscan very popular in use - They developed the composite order, which
combines Corinthian and Ionic capitals - They developed the giant order which spans up to
two storey and the miniature order used to
decorate windows - The Romans also contributed in the development of
the Triumphal arches - Triumphal arches were constructed in Roman cities
to celebrate victories in battles
118Materials, Const. Tech.
119Materials, Construction Tech. Materials
- The choice of building materials contributed to
the success of Roman architecture. - Roman building materials were very diverse and
rich - Materials that were not available locally could
usually be imported from other Roman colonies - Roman building materials included stone, marble,
brick, and timber - The art of producing fired brick was a Roman
invention - Romans also invented concrete
- The combination of concrete and brick formwork
enabled Roman architects to design and vast
buildings for different uses
120Materials, Construction Tech. Construction
- The Roman Civilization had the most innovative
construction system of the civilizations so far
studied - Roman architects understood the underlying
principles of arch and vault construction and
were able to innovate to address their
shortcomings - The combination of arch and vault construction
with concrete and fire brick formwork provided
the Romans with the technology to achieve their
architectural dreams - No previous civilization had an architecture that
involved the manipulation of space like that of
the Romans
121Materials, Construction Tech. Construction
- In fact, roman architecture was essentially space
shaped by vaults, and walls for the purpose of
ordered activities - In terms of building technology, the contribution
of the Romans includes the development of the
arch and barrel vault on freestanding piers. - Romans also introduced the use of timber trusses
in roofing - In the Pantheon, we find Roman construction
technology at the height of its application
122Materials, Construction Tech. Technology
- The greatest contribution of the Romans in
Building services and technology is in the aspect
of water - The development of the aqueduct enabled ancient
Romans to supply water to their cities - Rome at the height of its development had to
supply water to meet the needs of its one million
inhabitants - Along with water supply, the Romans developed a
system of waste water collection and disposal - Sanitary sewers were used to collect waste water
that is channeled outside the city for disposal
123Principles of Arch. Organization
124Principles of Arch. Organization Principles
- Three forces appear to shape the direction and
form of Roman architecture - Function
- Construction Technology
- Adaptation to new ideas and knowledge
125Principles of Arch. Organization Function
- The principal organizing principle of Roman
buildings is function - Function is evident in the emphasis on spaces
- Almost all Roman buildings provided spaces for
functional use - Roman architecture also de-emphasized the
rigidness in the use of the Greek orders - They transformed the orders from a determinant of
building form to decoration on gigantic buildings
126Principles of Arch. Organization Construction
Technology
- Understanding Roman buildings also requires
understanding their construction technology - Development in construction technology freed the
Romans from any creative limitations - They were therefore able to experiment, in the
process creating new building types and form and
also pushing the limits of structural
possibilities - Construction technology also allowed Roman
architects to produce buildings with vast
interior spaces - Construction technology enabled Romans to
transform the orders from structural elements to
mere decorative ones
127Principles of Arch. Organization Adaptation to
New Ideas and Knowledge
- Roman architecture can also only be understood by
understanding the Roman attitude to innovation - Romans were constantly in contact with different
people and places - As they come into contact the different people
and places, they are also exposed to different
ideas and ways of doing things - Roman people were always willing to lean new
ideas and knowledge and adapt these for their use
128Principles of Arch. Organization Adaptation to
New Ideas and Knowledge
- Such adaptation allowed them to assimilate ideas
from different places, including the Greeks, the
Egyptians and the Carthaginians - But when Roman people learn new ideas and
knowledge, they were also able to adapt them and
create ideas that were uniquely Roman - It is this will to learn and adapt that led to
their innovative social life and to the evolution
of Roman architecture
