Patras  is the third-largest city of Greece and the capital of the prefecture of Achaea, located in northern Peloponnese, 215 kilometers to the west of Athens. The city is built at the foothills of Mount Panachaikon, overlooking the Gulf of Patras.
The most significant, open to visit, ancient monument in Patras is the Roman Odeon, now reconstructed and used as an open-air theatre for performances and concerts during the summer period. Overlooking the whole town is the ruined Castle, whose current outline dates back to the Venetian invasion of the town (1687-1715). In current times, its interior is laid out as a public garden.
Close to the seafront, between the site of the new and the old port, there is the monumental church of St Andrew and in a projection of land stands a replica of the city's emblematic old lighthouse, built as a part of a coastline beautification project.
