Three noble families are linked with Dundonald Castle, but the association with the Stewarts (whose family provided the Scottish monarchs from 1371 onward) gives the castle special importance. In 1482 the castle and estates were passed to the Cathcarts, and in 1526 ownership changed to the Wallaces. By the end of the 17th century the castle was in ruins.

The real interesting fact is that this site was occupied well before 2,000 BC. On a clear day one can climb and stand on the ruined roof structure and see a spectacular view of Scotland. Fortunately.. the castle has been restored and enjoys many visitors during its open season.
The castle located on the prominent hill in Dundonald, Ayshire.. is the last of three medieval castles on this site, covering the period from early 12th century to 1647.
