Description
Corsehill Castle is a very ruinous mansion located on the outskirts of Stewarton. It was the seat of the Cunningham family and was likely designed in an L plan. The remaining structure consists of a single wall fragment that measures 5.8 meters long, 2.8 meters thick, and about 10 meters high, with a fireplace visible on the east side. This wall, considering the repairs said to have been made in 1840, closely resembles the wall depicted in Grose's illustration, confirming it as his "Corshill House."
To the west of the wall, there is a ditch that is 7 meters wide and has a maximum depth of 2.5 meters. South of this ditch, there are traces of another ditch about 3 meters wide and 1 meter deep, which appears to be the remains of a track that once connected the modern road on the west side of the castle to the cattle creep under the railway line on the east side. This track may have been original before it became silted up.
To the north of the site, there is a natural gully, and to the east, a rock outcrop that is now partially covered by the railway embankment. The rest of the castle is represented by irregular-shaped banks, through which fragments of masonry can be seen. These banks vary in height from 0.3 meters to 1.7 meters.
