Henry III loved building and complained that the privy chamber of his wardrobe smelt badly, and advised no one to build such a style again. A wardrobe was a small room next to the great chamber, usually with a latrine beyond a kink in the corridor.

Sometimes a scribe or secretary had to work in a wardrobe.
