Outer gatehouse and attached precinct walls and barn 50 metres north of Priory Farmhouse

The outer gatehouse and attached precinct walls and barn, located 50 meters north of Priory Farmhouse, date back to the early 14th century and were part of a former priory for Augustinian Canons. The structure is built from squared and irregularly coursed sandstone. While the original roof's gables remain, the rafters have been removed, and the building has a square plan.

The gatehouse stands two storeys tall. The outer wall features a first-floor window with two lights set in a two-centred chamfered arch, which includes fragments of reticulated tracery. Flanking this window are two 15th-century niches with trefoil cusping and engaged shafts. The carriageway has a three-centred arch with two chamfered arches on each face, and the inner arch mirrors this design, complete with a similar window above. The south-west angle of the gatehouse contains an octagonal stair turret from the 15th or 16th century, set in an ogee-headed arch. At the north-west angle, there is a small projecting wing that rises three storeys. The adjoining precinct walls are made of similar squared and irregularly coursed sandstone and feature gable coping. At the east end, part of the precinct wall is incorporated into the north side of a 19th-century barn, which is constructed of red brick and has a plain-tiled roof.

Inside the gatehouse, there is an original cross wall that includes a three-centred double chamfered arch leading to the carriageway, and to the west, a two-centred chamfered arch for pedestrians. The vaulting has diagonal and ridge ribs across three bays. The doorways are fitted with 19th-century plank doors, but they feature early 14th-century reset iron furniture.

The priory was founded in 1336 by William de Clinton, Earl of Huntingdon, and the site is designated as a scheduled monument.
