In the neighborhood of Agios Sasvas, walls are preserved, perhaps remains of public buildings and ancient temples, probably of Neptune. In the position Ellinika there are ruins of large buildings and an ancient tomb. In the position Kateros and in Drakospilio tower-like structures are preserved. Close to Panagia Spiliani the traces of a large well-built edifice of black trachyte, of the same style with Palaiokastro, are perhaps the ruins of a temple that would dominate because of its location on the island. Outside the gate of Palaiokastro there are ruins of an ancient temple, probably of Mercury, while close to Agia Triada they are believed to be of Meilichios Zeus. There are other remains of temples in the positions Kardia and Kampi.
