With its massive towers and battlements, the gray stone castle looks like something created by Disney, but it's the real thing. It has 130 rooms, its most impressive being the armory-filled Sala della Congiura (Conspiracy Hall). You can visit the theater hall, the court chapel, the 17th-century residence of various lords, the gatehouse, the knight's house, the keep, and the guard tower as well as the ramp wall. The castle is rather bare-bones inside, but worth seeing is the panoramic view from the tower, Torre Mastra. The entrance is from Via Termitana on a rocky spur.
