Description
Knucklebone Arbour is a garden building from the mid to late 18th century, located in Castle Ashby Park. It is constructed of timber and features a stepped conical thatch roof, forming a small rustic rotunda. The structure has slender circular posts covered with bark, creating a fluted appearance, with plain bases and bark capitals and frieze. One side of the arbour is open, while the other side has rustic planks made from split trunks between the posts and includes a low semi-circular bench inside. The floor is patterned with pebbles and sheep's 'knuckle-bones'. The eaves overhang the structure, and it offers a view across the park towards Castle Ashby. Access is provided by a walk through the boundary plantation, with a ha-ha separating it from the park. The arbour likely forms part of the landscape improvements made by Capability Brown. Castle Ashby park and gardens are recognized in the Historic Buildings and Monuments Commission Register of Parks and Gardens for Northamptonshire at Grade I.
