From Kastro, the highest peak of Chora, you can admire the panoramic view of Chora and the sea up to the nearby islands of Cyclades. Inside the Kastro there are several churches which are worth visiting, like the metabyzantine church of Agia Varvara, the church of Christ, Agios Konstantinos and Agios Ioannis in the basement of which lies - according to the legend - the head of Medoussa, left there by Perseus.
