Description
Dunglass Castle is a fragmentary castle located on an irregular rocky cliff by the River Clyde. The ruinous walls to the south and west of the castle enclosure may date back to the late 14th century. At the northwest corner of the enclosure, there is a dwelling house that is partly from the 16th century but mostly constructed in the late 19th century. The northwest turret of the house features chequered corbelling. In the opposite corner of the enclosure, a round tower, likely from the 16th or 17th century, appears to have served as a pigeon house.
The castle came into the possession of the Colquhoun family towards the end of the 16th century, who built the dwelling house within the fortified walled enclosure. The house was remodeled by 1832, which included the addition of a square two-storey bay in the west wall. Further enlargements took place between 1852 and 1861, with alterations made by Talwin Morris in 1893.
