This uninhabited island north of Karpathos is full of ruins from ancient times. It was also a Saracen/Arab base for Pirates dating from the 7th to 10th centuries, with remains of buildings from that era.
In the so-called Bay of Palaces lies an ancient tomb and an early Christian settlement with four basilicas, a vaulted tomb and a bath. North of the Bay, in an area called Kastello, there are some walls from an acropolis, as well as remains of a burial chamber and a Paleo-Christian church. In the area of Argos, on the top of the mountain there are remains of an abandoned traditional settlement.
