Ancient Greek architecture is represented by several famous temples from the 5th century BC including the Temple of Hera I in Paestum, Italy, the Treasury of the Siphnians in Delphi, and the Sanctuary of Apollo in Delphi. The Acropolis and Athenian Agora, built in the mid-400s BC, were centers of civic and religious life in Athens. The Theater of Epidauros, built in the 300s BC, hosted healing performances for up to 14,000 people.
