Today the island is uninhabited: it is a vast archaeological site whose superb monuments draw thousands of visitors in pilgrimage to what was, for a thousand years or so after the ninth century BC, the political and religious centre of the Aegean. The archaeological site covers almost the entire island, starting on the west side, where the sacred harbour was. From the harbour, a majestic sacred way led to the Sanctuary of Apollo, where there were temples, altars, votive offerings and other buildings. There are ruins of four temples to Apollo, one of them known as the Temple of the Athenians.
