The Roman Odeon is located on the west side of Patras. It was built before the Odeon of Athens and there was a statue of Apollo inside it. The Odeon of Patras was severely destroyed by successive invasions, wars and earthquakes. It was almost buried under the remains of other buildings and ground. It was in 1889, when the Odeon was found by accident while some workers were digging up the ground for the construction of the port. The restoration of the Odeon continued until 1956, when it regained its original shape. Along with the restoration process of the Odeon, the nearby areas were declared as archaeological sites. The Roman Odeon today functions as the chief venue for the Patras International Festival, held every summer. The Odeon has a capacity to hold 2,300 people, with all basic facilities of a theatre such as hollow, orchestra, proscenium, scene and wings.
