This is behind the Great Hall, where a "huge hall stretches for 120 m. taking one whole side of the inner fortifications and looping around to the north to join the chapel. This hall probably served multiple purposes: kitchens (there is also a well and a bread oven at the south end) [...]. This structure is within the immediately post-1170 Crusader construction forming the basic shape of the central fortress." (Ross Burns' The Monuments of Syria).

This is looking back south, the loop is obvious, in our back the entrance to the chapel is approaching.
