Summer School Location

The city of Patras is located in the NW Peloponnese, 213km west of Athens. It is the capital of the prefecture of Achaia, the largest city in the Peloponnese and the third largest in Greece. Patras is Greece's "Gate to the West", it's harbour connecting the whole country with the ports of Western Europe. The city's history can be traced back to the second millennium B.C. and the Mycenean civilizations, but it is during the 19th Century that the city flourished and became an important centre of commerce. Patras is interesting and attractive with archaeological sites and neoclassical buildings blending with modern residences and commerce. Places worth seeing in Patras include the Fortress, the Roman Odeon, the archaeological and folklore museums, St. Andrew's Cathedral, the Municipal Theatre and Gallery, and Achaia Clauss winery. Today, the city is an important cultural centre where the Hellenic Open University plays a leading role.
