The “sunken city” of Old Epidaurus (Palea Epidavros) is composed of a set of buildings, between 1-2 meters of depth under the sea, about 20 meters from the coast, in a Old Epidaurus beach in the east of Peloponnese, in Greece.
The jewel of the sunken city is the Roman mansion, where there are remains of wine amphorae.
The place is free of charge and open 24 hours a day.
