Ruins
Temple of Poseidon
The Ancient Greeks knew how to choose a site for a temple. At Cape Sounion, 70km south of Athens, the Temple of Poseidon stands on a craggy spur that plunges 65m to the sea. Built in 444 BC – same year as the Parthenon – of marble from nearby Agrilesa, it is a vision of gleaming white columns. Sailors in ancient times knew they were nearly home when they saw the first glimpse of white; views from the temple are equally impressive.
