RomanArchitecture


Arches

  • The Romans used arches to support the things they built.

  • They built victory arches, buildings and aqueducts.


Aqueducts


Aqueducts- a 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


Arches of Triumph-to celebrate military success


The Coliseum-a place for sports


The Coliseum- 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.


The Pantheon-a temple to all the gods


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.
