Below the hall was a richly decorated vaulted cellar with direct access to a wharf on the River Thames for bringing in supplies. Royal visitors were entertained at the palace, including King James I of Scotland on his wedding to Joan Beaufort (niece of the then bishop, Cardinal Henry Beaufort) in 1424. The palace was arranged around two courtyards. Other buildings within the site included a prison, a brewery and a butchery. The palace environs comprised a garden, a tennis court and a bowling alley.
