Castle of Profitis Elias

site of Profitis Elias, inside the fortification enclosure, remains of stonework are preserved but cannot be dated. At the northern end of the acropolis, a small unprotected dry stone building measuring 5x3 with a rudimentary altar is preserved on the outline of the ruins of the old one-room temple of Prophet Elias. According to the surface findings, the area has been inhabited since at least the Hellenistic Period. The final configuration of the fortification took place during the Venetian period, perhaps around the 15th century like most Venetian fortresses in the Cyclades. Surface finds are of various periods, prehistoric (mainly on the north-western slope), Hellenistic and Roman, mainly on the western slope of the hill, where many unsealed amphora handles were also found.
