Chora has been permanently inhabited since classical times. Folegandros belonged to the Athenian Alliance in the 5th century BC. In fact, where the church of Panagia is located today, there was a temple dedicated to the god Apollo. During the same period, the cave of Chrysospilia acquires a religious character, where adolescent coming-of-age ceremonies took place. Interior is decorated with stalactites and stalagmites. Furthermore, there are remains from antiquity: vases and their fragments, lamps, etc.
