Bent entrance
A bent or indirect entrance is a defensive feature in
medieval fortification.[1] In a castle with a bent entrance, the gate passage is narrow and turns sharply. Its purpose is to slow down attackers attempting to rush the gate and impede the use of battering rams against doors. It is often combined with means for an active defence, such as machicolations, in effect confining intruders to a narrow killing zone. Its defensive function is related to that of a barbican
in front of the gate.
Indirect entrances are typical of Arab and Armenian fortifications, as well as
Belvoir
, posterns open into the moat at the angle between the outer wall and the corner towers.
Bent entrances of such complexity as at Crac are less common in European castles, where even in strongly defended
murder-holes
, but no turns. Cathcart King has argued that the indirect entrance was less widespread in Europe than in the Crusader states because transport in Europe tended to be based on carts pulled by draft animals, which makes negotiating a twisting passage impractical, whereas camels, as used in the East, would have less difficulty.
