The castle at Knucklas is mentioned in 1248 and 1262. The surviving remains are located at the highest point of an irregular hilltop enclosure measuring approximately 183m by 124m and defined by scarps, doubled to the south and east. This is possibly an Iron Age fort. Within this earlier enclosure the medieval castle earthworks are subrectangular, c.23m by 40m but truncated by quarrying to the southwest. There is an inner scarp that defines a platform, 20m by 23m.
