Cape Sounion, at the southern tip of the Attica Peninsula, is a steeply ending headland looking out over the Aegean Sea and its many islands. At its head is the white-marble Temple of Poseidon, dedicated to the god of the sea and surrounded on three sides by water.

Scenically placed, well-preserved and close to Athens, the Temple of Poseidon offers an incredible sense of place, a sentiment captured by Lord Byron in his poem The Isles of Greece. A cluster of seafood restaurants and sandy beaches add to the appeal.

Built in 444 BC, during the Golden Age of Athens, the Temple of Poseidon sits atop an outcrop, surveying the sea. According to legend, this was the spot where Aegeus, king of Athens, flung himself into the water when he saw his son Theseus’s ship returning from Crete with black sails and mistakenly believed him dead. Theseus had agreed to fly a white sail had he successfully defeated the Minotaur but, distracted by love, forgot to switch it over.

The cape is a sacred site in many ways. When the Athenians defeated Xerxes in the Battle of Salamis in 480 BC, they placed a captured enemy warship on the headland and dedicated it to Poseidon.

Later, Pericles, the statesman responsible for rebuilding the Parthenon in Athens, commissioned a temple on the spot. He probably used Iktinos, the architect of the very similar Temple of Hephaestus in Athens' ancient Agora, to design the tribute to the sea god.

White marble for the temple was quarried nearby, giving it an arresting, bright appearance that made it an important landmark for sailors returning home. Originally, the temple had six white columns beneath the portico and a colonnade of columns on all sides.

Today, 16 of the original Doric columns remain, giving you a good impression of the size and scale of the newly built temple. Its setting, 60 m (200 ft) above the sea, is what lends it its undeniable drama and grandeur, though.

The views from the site are given over to the deep-blue sea and sky, only interrupted by the craggy tips of the islands of the Saronic Bay. On a clear day, the views from the site are far reaching, with the isle of Kea and the Peloponnese visible in the distance.

Lord Byron was so impressed by Sounion that he carved his name into one of the stones at the base of the temple. You can still find it among other graffiti of the age. At sunset, when the crowds have eased and the view across the water from the ruins glows a deep red, it’s easy to see why he was so taken with the place.

Nearby, the scant remains of the Temple of Athena stand on a low hill, built in 470 BC. The temple was destroyed in the 1st century AD, but you can still see its foundations. From here, a path leads down to a small sandy beach, though there are other larger beaches to the west.
