Ardstinchar Castle is said to have been built by Hugh Kennedy in the middle of the 15th century. Now reduced to a fragment of the keep and a few wall foundations, it originally occupied an irregular platform circa 120' square. The gate was apparently at the NW angle, and the keep occupied the highest point at the eastern angle. About 1770 the castle was used as a quarry for material for a bridge over the R Stinchar.
