According to historic engravings, the shape of the castle appears to be triangular or quadrangular, with strong large towers on all corners. Furthermore, it appears that there are also buildings inside the castle. In fact, in the Camozio(1574) and Coronelli’s (1688) engravings there are also a mosque and a large circular building. However the current situation cannot match this information, given that the castle’s size is too limited to allow further buildings inside the fortification.
