Go down the first long flight of steps from the cavalier to arrive again at the small terrace. Opposite the long staircase is a narrow passage between two blocks of barracks. Walk through this passage until you reach another set of stairs. Go down the steps and turn left. About three metres ahead, is another display room. The shaft at floor level between the display rooms is the guva, or oubliette. Stand in front of it and listen to this next set of stories.
