Cape Sounion is a promontory in southern Greece on the Aegean Sea about 70 km (43 miles) south-east of Athens, and noted primarily as the site of the ruined Temple of Poseidon. The temple is located on a craggy spur, overlooking the sea about 60m (197 ft) below. It was built in the 5th century BC at the same time as the Parthenon in Athens and was the focus of an important sanctuary to the sea god. Sixteen of its 34 Doric columns are still standing; other remains include parts of a protective wall surrounding the sanctuary and of a propylaeum, or entrance hall, with a portico.
Landing to visit the Cape rather than just sailing past will be from the industrial town and ferry port of Lavrion.
