Prudhoe Castle

Prudhoe Castle is a historic castle primarily dating from the 12th and 13th centuries, with a 14th-century barbican and an early 19th-century manor house. The structure is built from squared stone, with the manor house featuring dressed stone and a stone slate roof. The inner and outer baileys are now separated by the Gothic manor house, the keep, and the gatehouse with the barbican.

Access to the castle is through an elongated barbican that has an outer pointed arch leading to a round-headed tunnel-vaulted gate passage beneath a rectangular tower. The first floor of the chapel features an important early canted oriel window and lancet windows on the east side, along with a guard room above and an external stair leading from the ground to the roof. The curtain wall is largely intact and includes various features related to former internal buildings, with recently exposed foundations. Notable elements include a shouldered-arched opening to a well-preserved garderobe on the south side. The east tower has been Gothicized in the late 18th century.

The manor house is two storeys high with five bays and includes a round-arched carriage entry to the inner ward on the left. The right bay has a six-panelled door with a four-centred head and fanlight, while similar heads adorn the windows, which are sashes with intersecting glazing bars. The left return of the manor house is embattled and incorporates earlier masonry, featuring two 2-light 15th-century windows. The right return is apsidal and embattled, with three stone ridge stacks.

The inner bailey features a well-preserved curtain wall with a round tower at the north-west corner and the base of another at the south-west corner. The ruined keep, which is relatively small at 41 by 44 feet, is linked to the manor house by the remains of a forebuilding. The south-west corner of the keep is intact and has a crenellated angle turret, with a mural stair in the west wall and two shouldered-arched openings in the north wall. There is also a well-preserved garderobe on the north curtain wall. Additionally, there is a range of early and mid-19th-century outbuildings against the west wall.
