Acrocorinth is a monolithic limestone rock formation located 575 meters above sea level, serving as the acropolis of ancient Corinth. The site contains successive layers of fortifications dating from the Archaic, Byzantine, Frankish, and Ottoman periods.

The site is accessed via a steep path leading through three consecutive gatehouses. Its strategic position offers panoramic views over the Isthmus of Corinth, the Gulf of Corinth, and the Saronic Gulf. The site is currently maintained as an open-air archaeological park.
