Castle Barn Approximately 50 Metres North East of Thorpe Castle House

Castle Barn, located approximately 50 meters northeast of Thorpe Castle House, is the great hall of a castle that dates back to the early 14th century, originally associated with Walter de Langton, the Bishop of Lichfield. The building is constructed from squared coursed limestone and features a thatched roof. It has a rectangular plan and was likely originally designed as a hall and solar range, with two storeys, although the first-floor structure has since been removed.

The west elevation includes a central 19th-century cart entrance, an ashlar plinth, and ashlar gable parapets. The left gable has a projecting chimney breast that is corbelled out from the first floor level, topped with an octagonal crenellated flue on a square base. At the attic level, the chimney breast is flanked by deeply recessed circular windows with moulded surrounds, while the right gable features slit vents. The rear of the barn also has a central cart entrance from the 19th century.

Inside, the barn boasts a very fine king-post roof structure. The tie beams are supported by wall posts and curved braces, with the king posts featuring braces in both directions and similar braces opposite the collars. The main beams have moulded soffits and there is a moulded cornice. Evidence of a screen in the roof structure is present in the northern bay, along with signs of a first-floor fireplace in the north gable wall. The roof structure of the hall range shows smoke blackening. A two-storey gabled porch is believed to have been removed in the 19th century. Walter de Langton was granted permission to crenellate the building in 1301.
