The fortress is characterized by large square towers and scarp walls, which would have fed into a moat. The city entrance was offered by a double
ravelin with
drawbridges, adorned with a coat of arms, likely sculpted by an artist from
Veneto. Malatesta's name is written to the left and right of the coat of arms. Large marble epigraphs in the walls pay tribute to Malatesta. The walls were thought to be thick enough to bear the impact of the new artillery pieces of that period. Although originally positioned externally from the city, it has no towers facing that side: all towers are oriented towards the city. These towers are square, and once housed a bronze cannon each. The central part of the castle was also the Malatesta residence, with rooms decorated with tapestries, curtains, and frescoes. Also, the exterior was decorated, as suggested by the few
maiolica tiles visible. ==References==
