The Roman Odeum in Patra Peloponnese: The Roman Odeum is located on the west side of Patra. It was built before the Odeum of Athens in front of which stands the statue of Apollo. The Odeum of Patra 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 Odeum was found by accident while some workers were digging up the ground for the construction of the port.
The restoration of the Odeum continued till 1956, when it regained its original shape. Along with its restoration process, the nearby areas were declared as archaeological sites. The Roman Odeum today functions as the chief venue for Patras International Festival held every summer and other cultural events. The Odeum has a seat capacity of 2,300 people with all the basic facilities of a theatre such as hollow, orchestra, proscenium, scene and wings.
