قلعة حلب
Indirect entrances are typical of Arab and Armenian fortifications, as well as crusader castles. The Citadel of Aleppo is a good example of the former, with a massive gate tower enclosing a complicated passage. The most elaborate bent entrance among crusader castles is the turning entrance ramp at Crac des Chevaliers, which is defensible from several towers and via machicolations, but the indirect entrance to the Hospitaller castle at Bethgibelin is also complex. In addition to the main gate, postern gates could also feature a bent entrance, usually on a smaller scale. For instance, in the ruined Hospitaller castle at Belvoir, posterns open into the moat at the angle between the outer wall and the corner towers.
