The Theater of Delphi is built on the side of the hill just further up from the Temple of Apollo. This position gave a magnificent view of the sanctuary including the valley below. The theater is one of the few theaters in Greece which we know information about its exact date of construction, design and use thru the centuries. It was built in the 4^th century B.C, to host the theatrical and musical events and contests of the Pythian Games thus forming an integral part of the sanctuary. In 160 B.C, Eumenes II of Pergamon repaired and restored the theater, giving its present day form.

It had 35 rows with a capacity to seat 5000 spectators, and divided into two sections by a horizontal path used to assist the movement of spectators in the theater.
