They became famous for their architecture—the way they designed and built buildings. The Greeks built enormous buildings from marble. One of the most famous Greek buildings is called the Parthenon. The Parthenon was a temple built in honor of Athena, the Greek goddess of war. Its ruins still stand in Greece, in the city of Athens, on a hill called the Acropolis. Inside the Parthenon were pictures, carved in marble, of different Greek battles.
