The city isn’t considered to have much to offer tourists but you may disagree after visiting the site of the production of the famous sweet wine, Mavrodaphne of Patras which was founded in the 19th century. There’s also the Roman Odeon which took nearly sixty years to unearth and restore after it was found under other buildings on the site.
The archaeological museum is especially of note, and not just for its exhibits. The building is considered an icon of modern design in shiny titanium and is now a major talking point of the city. Southeast along the gulf you’ll come to Corinth itself, home of the Corinth Canal which is incorrectly thought of by many as an ancient site but which was actually completed around the turn of the 20th century although the idea was put forward in the 1st century AD.
Travelling via Pyrgos from Patras you’ll come to Olympia which was the home of the first Olympics and where today, the Olympic torch is still lit.
