The hill on which the ancient city was located extends to an altitude of 327 metres. Ruins of the town, the city-state of Anafi, can be seen there. The city was probably established in the 8th century BC by Dorian colonists and was the dominant city of the island until the end of antiquity.
The city walls, as well as extensive ruins of the city’s cemetery, can be seen at Kastelli. Rich findings from the Roman period, during which the island flourished, are scattered throughout the area; one particularly impressive finding is the sarcophagus located next to the historic chapel of Panagia sto Dokari.
