Sherburn Hospital Gatehouse, office wing, lodge and wall

The site comprises a 14th-century gatehouse, a mid-19th century lodge, a late-19th century office wing, and a boundary wall, forming part of Sherburn Hospital. The hospital was founded around 1181 as a leper house and suffered damage during the Civil War.

The gatehouse, originally of the 14th century, has an upper floor rebuilt in 1896. A section of possible 14th-century buttressed wall survives. The mid-19th century lodge and the office, dating from around 1896, flank the gatehouse. The building materials are dressed and ashlar sandstone. The office has a graduated stone-tiled roof, the lodge has a Welsh slate roof, and the gatehouse roof is not visible. Stone chimney stacks are present. The buildings are arranged in an L-shape, with the office on the left return of the gatehouse and the lodge to the right. The office and lodge are in a Tudor style.

The two-storey gatehouse features a square plan with angle buttressing. It has a pointed, double-chamfered archway under a hoodmould, leading into a pointed tunnel vault supported by three chamfered ribs. The low upper storey, rebuilt as a muniment room, has a two-light mullioned window and an embattled parapet with gabled copings. An early 19th-century pointed archway is on the rear elevation.

The single-storey, two-bay office has two- and three-light ovolo-mullioned windows and a steeply-pitched roof with overhanging eaves. A tall corniced ridge stack is present. There is a Tudor-arched doorway, with an identical doorway in a projecting porch on the rear.

The single-storey, one-bay lodge has a lean-to bay added on the right. It features a 19th-century pointed doorway on the left return, with two-light mullioned windows under hoodmoulds. The building has tall, flat-coped parapets. A bay projects on the rear. Later 19th-century sheds are attached to the front of the lodge and built against the interior of the wall.

The tall, flat-coped, L-plan wall is approximately 8 metres high. A section on the front of the lodge has three regularly-spaced, two-stage buttresses with offsets. A short return section to the right also features an identical buttress.
