Ardencaple Castle

Ardencaple Castle is a building with earlier fabric that was significantly reworked, likely by Robert Mylne in 1786 and later by Peddie and Kinnear in 1877. The castle features a four-stage square corner tower with battlements, which was retained after the main castle was demolished in 1957. It is constructed from whinstone rubble with pink sandstone ashlar dressings and a parapet. The base course is battered, and there are bipartite windows with pointed lights that are now blinded, along with hoodmoulds on the east, west, and north elevations. The tower has a corbelled and crenellated parapet.

On the east elevation, there is a two-leaf door and a window on the first and second stages, with an armorial crest on the upper stage. The west and north elevations each have a window at the ground, first, and second stages, while the south elevation has blocked windows. Overall, the windows are blinded.
