Mowbray Castle

Mowbray Castle is a folly built around 1750 for William Aislabie. Constructed from ashlar and rubblestone, it stands 2 to 3 storeys high and has an oval shape. The building features three bays, with offset angle buttresses flanking the central bay, while the outer bays consist of the remains of rubble walls. The central bay has a large pointed-arched opening, which is flanked by smaller, thinner pointed-arched openings, all with raised imposts.

On the first floor, there is a band with a central cross-shaped opening, a pointed-arched opening to the left, and a smaller blind pointed-arched opening to the right. The second storey has similar openings with projecting sills, but these are now in a ruinous condition. Above, the remains of an eaves band and a parapet can be seen. The returns of the structure have cross-shaped openings on the first floor, with pointed-arched relieving arches leading to the interior. The building was derelict at the time of the last survey. For historical context, refer to Fishers Hall, Hackfall, item 5/21. Mowbray Castle is located within the Grade I listed Hackfall on the North Yorkshire Historic Gardens Register.
