As in other major Norman keeps, this level actually forms a double story with a mural gallery running most of the way around the upper stage. A number of private chambers are contrived within the great thickness of the walls off the hall and solar. One of them contains a well, the shaft of which sinks 350 feet into the underlying chalk. A passage leads to another chapel, even more delicate than the one immediately below it, and showing signs of the transition to Gothic architecture. The floor beneath is similar in layout, including the mural chambers.
