Description
The walled garden at Knock Castle was probably remodelled or rebuilt around 1852 by J T Rochead. It is a rectangular garden enclosure defined by yellow brick walls topped with red ashlar coping slabs. Red ashlar gatepiers, also castellated, support wrought-iron gates. A long glass house range runs along the north wall, featuring a distinctive polygonal centrepiece. A castellated turret is centrally located on the west wall, accessed by steps from the garden, and featuring four round-headed openings. A continuous string course sits above these openings, rising to a corbelled and crenellated parapet.
Historical records, including a plan from 1847 in the Strathclyde Regional Archives (T-PM 134/113), show a simpler rectangular garden enclosure originally existed on the site. The turret is marked on the first edition Ordnance Survey map of 1854.
