Citadel
The citadel of the fortress, occupies an area of approximately two acres having its own quadrilateral fortification. Its southern walls are preserved at a maximum height of 13 meters and, at its highest point, rises the today’s ruined tower built by Andronikos Palaiologos the 3rd.
The tower of the citadel was a two-storey building and today survives at a height of approximately 7.5m., with dimensions of 13.46X9.40m. On the ground floor there is a double-vaulted water tank and on the first floor a mural chapel. It was accessed by a wooden mobile ladder.
The chapel was located on the first floor of the tower. Fragments of murals were found during excavations, and among them, a small shard bearing the monogram of Palaiologos. This fragment comes from the founding inscription of the Tower and has an talismanic character.

The vaulted tank is preserved on the underground level of the tower, and has a capacity of about 176 sq.m. It was used as a rainwater cistern and supplied the fortress with water.
