The Archaeological Site of Sounion is a must-visit for those interested in Greek history and mythology. Cape Sounion was a strategic point where Athens controlled sea passage to the Aegean Sea and Piraeus, thanks to rich silver mines. Inside the fortress is the sanctuary of Poseidon and Athena and ship sheds for warships. Scholars like W. Dorpfeld and Valerios Staes excavated the site. Restoration of the temple of Poseidon began in 1874 and was completed in the 1950s. A visit to Sounion is a journey through time and ancient Greek culture.
