The ground floor was just an undercroft for storage, the principal accommodation lying on the floor above. Owing to its importance, the first floor rises through two stages, giving the illusion of three stories in all. The keep is divided longitudinally by a cross wall, thus separating the hall from the solar on the first floor. Stone vaults support a kitchen and pantry at one end of the hall, and another vault supports a chapel beyond the solar. A gallery runs along one wall at hall level.
