The Fortress compound is divided into two levels. In the lower level there is a three-storey building called "Punta Perpetua" and a bastion of pentagonal shape. Inside the bastion there is a maze of arched chambers, galleries, ventilation shafts, stairs and ramps. The fortress has two
baroque-styled gates. Its western side features a dry moat which spans the length of the walls, running from the vegetable market to the new harbour. The moat is a good example of moat architecture. The structure features twin bastions, named
Skarponas and
Epta Anemoi ("Seven Winds"), which has a commanding view of the sea and the mountains of mainland Greece. Below the bastion there is a building which was built by the British and functioned as military barracks. Nowadays it houses art exhibits and collections as well as space for social events. The bastion is at a height of 55 m above sea level and features structures such as underground cisterns, powder magazines, artillery positions and underground halls. ==Governor of the castle==
