Skíathos - Kástro

Two and a half hours' walk north of the town of Skíathos (also accessible by boat), on an impregnable crag are the ruins of the island's medieval capital, Kástro. Of interest are stretches of the town walls, with a drawbridge, Turkish baths and three of the 22 churches the town once possessed, including the church of Christós sto Kástro (17th C.; frescoes).

In the 16th century the whole population of the island moved to the impregnable rock which rises to the northeast of the town of Skíathos and built their Kastro. A drawbridge was its only link with the rest of the island in the old days, but today it can be approached by climbing up some steps. Its walls once enclosed 300 houses, although none of these remain.
