The wall-paintings were discovered under whitewash in 1936. The most important of them are the arabesque drawings in the Mermaid Passage and on the back staircase and the figures of the Nine Worthies on the second floor. The Small Chapel is decorated with red and white drops for the blood and water of the Passion and there are also traces of medieval work.
