 The Hospitium is located between the ruins of St. Mary's Abbey Church and the River Ouse and is thought to have originally been a guest house for visitors to the abbey of low social rank, or possibly a barn.It was originally part of a group of buildings in the abbey grounds that included a brew-house, stables, mill and, near the main gate, a boarding school with 50 pupils.The oldest parts of the ground floor were built around 1300, but the upper storey has been extensively restored in modern times.
