Stanage Park is located some 3 miles east of Knighton, Powys and near the settlement of Heartsease.
It is an outstanding picturesque parkland laid out by Humphry Repton. The last and most complete of his three recognized Welsh landscape commissions. Repton's picturesque parkland improvements, castellated house and enclosed garden survive almost intact and are recorded in a 'Red Book', still kept at the house. Later nineteenth-century arboretum and formal terraced gardens lie to the north and west of the house.
The house itself is a Grade II* listed building.
