The Benedictine priory at Boxgrove, close to the South Downs, was founded around 1107. All that survives are the roofless guest house and parts of the church and chapter house.  The lodgings originally had two storeys, with an undercroft, or vaulted cellar, used for storage. The support for the vault of the undercroft can be seen clearly at the north end of the building. The priory church became Boxgrove’s parish church after the Suppression of the Monasteries and remains in use today.
