On 7 August 1563, Mary, Queen of Scots, stayed at Ardmillan before moving on to Ardstinchar Castle.[1]
The original structure was built in the late 16th century on a low mound. It was originally a rectangular tower with circular towers on the corners. The two northern towers have been removed.[2]
It was built and owned by the Kennedys of Bargany until 1658, it then passing through marriage to the Crawfords of Baidland. By 1688 it had a motte (wide ditch) built on all sides.[3]
In the 18th century a classical wing and new formal front was added and it took on more of the appearance of a house rather than a fortification, and was sometimes referred to as Ardmillan House.[4]
By 1892 it had an enclosed courtyard built at its base.[5]
It suffered in a fire in the early 20th century and again in 1973 leaving the property ruinous. The grounds have been used as a caravan park since 1980.[6]
