Famed for its sunset, the southernmost headland of Attica hosts one of the most important temples of the ancient world, the Temple of Poseidon, god of the sea. At an altitude of 60 m above sea level, it is the last landmark you can see when you leave Attica by boat, and the first when you are arrive. According to legend, it was from this rock that King Aegeus of Athens fell into the sea when he mistakenly thought that his son Theseus had been killed by the Minotaur. As well as the temple, the archaeological site also includes ruins of fortifications, ancient relics and a smaller temple dedicated to the goddess Athena. The Doric temple of Poseidon was built at the same time as the Parthenon, between 444 and 440 BC.
