The outer wall runs diagonally from the northwest parapet, turning southward as it skirts the main courtyard. Here, the upper rampart has fallen into complete ruin -- first weakened by enemy bombardment, then broken off in the final assault and toppled into the moat. In spite of the damage, a rickety wooden ladder still leans against the crumbling wall-walk.
