Twin Reservoir
The vaulted tank is preserved on the underground level of the tower. It is developed in correspondence with the rooms of the tower floor and has a capacity of approximately 176 sq.m. Its walls are coated with a double layer of hydraulic mortar. Access to the cisterns for their cleaning is by a stone-built staircase from the western room. Narrow passage that opens at a height of 50cm. from the bottom of the tanks serves their communication. A series of openings in the outer walls of both rooms help to ventilate and illuminate them. The tanks collected the rainwater and served the water supply of the fortress, especially during periods of long siege.
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.
