4. Doric Ionic Corinthian

5. Roman Concrete The Roman’s invented a new building material that we still use today, concrete. They mixed stone, sand, lime mortar and water. It dried and hardened into concrete. The surviving Roman monuments testify to the strength and durability of concrete.

6. Arches The Romans made great use of the Etruscan Arch The Romans used the arch in various ways. They used it to create architectural structures of great size and strength. The vault was created by putting a series of arches side by side.

8. The dome was created by several arches crossing in different directions in a circular space. Arches and Concrete revolutionized Roman architecture. The Arch can be seen in the construction of city gates, bridges and aqueducts. As well as theaters and ampitheaters (round theaters).

9. Colosseum It was the most famous example of an ampitheater in Rome. Emperor Vespasian started construction in 72 A.D and completed it in 80 A.D.

11. Aqueducts It is a water transport system that allows water to flow through pipes or channels to carry water from a well or stream into the town. The water was distributed throughout a complex system of lead or earthenware pipes.

12. It moved the water using gravity –The aqueduct had to be built at exactly the right angle in order to use gravity to its full potential. –It was important for the route of water to be constant and running. They were used to bring water to areas that did not have natural water resources.

13. The Pont de Gard Was a masterpiece built and named for the Gard River. It channeled water from Nimes, France. Highest of all Roman aqueducts. It consisted of three tiers of arches The Pont de Gard is a testimony to the engineering and construction skill of the Romans.

14. Pantheon The Pantheon dates back to 27 B.C., when it was first built by Marcus Agrippa. Emperor Hadrian rebuilt it between 117-125 A.D. after it burned to the ground in 80 A.D.
