Ancient Greek architecture developed between 900 BC to 1st century AD and was influenced by earlier civilizations like Egypt. The Greeks used post-lintel construction and three classical orders - Doric, Ionic, and Corinthian. Temples were the main buildings and were used for religious purposes to show power. Other structures included houses, theaters, and markets. Materials included bricks, stone, wood and marble. Architecture progressed through Geometric, Archaic, Classical and Hellenistic periods, with innovations like stone temples and complex theater designs in the Archaic and Classical eras.
