Arthur's Hall, adjacent to the north-east wall of the inner bailey of Dover Castle, was built in the late 1230s and was a building of significance until the 17th century. The building has undergone many phases of alteration (most recently in the C18th when it was refaced and a second floor was added for barrack accomodation). Despite this there are the remains of medieval building material in all of its walls, with numerous features which highlight its former uses.
