Roman
Architecture
Arches
• The Romans built
arches for support
of their
structures.
• The Romans built
arches into all
their buildings
such as aqueducts
and Triumphal
Arches.
Aqueducts
Aqueductsa way to carry water
• There wasn’t enough water in the city
of Rome.
• The Romans brought water in from
the surrounding countryside.
• The water was brought in by tubes
called aqueducts.
Why arches?
• Water is heavy
stuff.
• The Romans needed
a structure strong
enough to hold all
that water to move
it from the
mountains into the
city.
Where did the water go?
• The water was
transported in
concrete tunnels.
• The tunnels were
underground if
possible.
• Sometimes the
tunnel had to go
above ground.
How did the aqueduct work?
• The water flowed
in a tube on the top
of the aqueduct
called a water
channel.
• The arches
supported the
water channel.
What did the water channel
look like?
• The water flowed
through a
rectangular
channel.
• The channel was
lined with concrete.
• The Romans
invented concrete.
Where else did the Romans
use arches?
•Arches of Triumph
•Buildings
•Roofs
•Windows
•Doorways
•City wall entrance doors
Arches of Triumphto celebrate military success
An Amphitheatre;
a place for sporting and gladiatorial
events. They were always circular. The
one in Rome was named the Coliseum
and could hold 50,000 spectators.
The Coliseum was a blend of
Greek and Roman
architecture
• The arches are
supported by central
columns.
• The columns on the
first floor are Doric.
• The columns on the
second floor are Ionic.
• The columns on the
third floor are
Corinthian.
Wealthy Romans, called patricians had
the best seats. Middle-class citizens
called plebeians, sat in the higher
seats. Slaves, if they could afford it,
sat in the highest seats.

How does an arch work?
Keystones
• The keystone is
the red stone at
the top of the
arch.
• The keystone is
what the weight
rests on.
How does an arch work?
Voussoirs
• The semi-circular
stones on either
side of the
keystone are the
voussoirs.
• The voussoirs bring
the weight to the
columns that go to
the ground.
How does an arch work?
Buttressing
• The square or
rectangular blocks
between each arch
are buttresses.
• The buttresses
make a column that
takes the weight all
the way to the
ground.
