The Acropolis in Athens was a sacred hill dedicated to the goddess Athena that held important structures like the Parthenon. The Parthenon was designed by Pheidias and built almost perfectly out of marble with 46 surrounding pillars. Other temples in Athens included the Erechtheion, Hephaisteion, and Olympeion dedicated to various gods. Pheidias also designed statues for the Parthenon and Olympia. Greek architecture used three pillar styles - the plain Doric, spiral Ionic, and leafy Corinthian. Athenians excelled not just in architecture but also arts like sculpture decorating temples and pottery depicting everyday life that was traded widely.
