According to Wikipedia
The massive arched bridge built by Sultan al-Zahir Ghazi over the trench led to a complex design of the entrance. Any attacker of the castle must pass more than six turns to reach the slope of the vaulted entrance, where the niches fired the attackers at the top. The main corridors are decorated with pictorial inscriptions. Above the Ayyubid Gate Tower is the Mamluk throne hall. [18]
