ancient roman stuff

The roman people excelled in art and architecture, partially because they assimilated all the good stuff from all the people that they conquered; and they conquered a whole lot of people. They used archs, vaults, and concrete better than  ayone else.

here we see an image of a roman arch, an arch is a curved architectural element used to span an opening. The romans would have made this out of concrete.

this is an example of a roman vault, a vault is an arched roof or covering made of brick, stone, or concrete.
