For a civilization so closely aligned with the Mediterranean, it is remarkable there are no temples in Athens dedicated to Poseidon, the god of the sea. However, on the rocky peninsula of Cape Sounion, which juts into the sea at the southeast tip of Attica, the Athenians built him a sanctuary – as well as two to the goddess Athena, patron of their city – that today stands as one of the most remarkably situated of all classical ruins. Built on the summit of the rock, which rises 200 feet out of the water, and surrounded by stout walls, the Temple of Poseidon at Sounion keeps watch over the great expanse of the Aegean. As you’d expect, it’s also a magical place to watch the sun set. Click the panoramic image, then click again for greater detail.
