The Greek architecture is most known for its temples. One of the most famous temples is called the Parthenon. There is a replica in Nashville, TN. My opinion personally is that the original is way cooler. Another ancient structure is still being used, called The Ancient Theatre of Filippoi. It is still being used for annual festivities.
Roman is one of the first built on architecture types. What I mean by "built on" is that it was one of the first architecture pieces that really stood out. Architecture of all kinds built on to Roman. Almost all kinds of architecture have a little bit of Roman, Greek, and Egyptian in them. One of the most famous architectural piece is the Colosseum.
Renaissance means "Rebirth".
