Sundrum Castle is located 1.5 kilometres north of Coylton. It was originally built in the 14th century for Sir Duncan Wallace, Sheriff of Ayr, and considered one of the oldest inhabited castles in Scotland. Long-term owners included the Cathcart family, and the Hamilton family, who expanded it the 1790s, incorporating the original keep into a mansion.
It was further expanded in the early 20th century by Earnest Coats. For a time it was then a hotel, though fell into disrepair. After extensive renovations in the 1990s, it was split into multiple privately owned properties. The Sundrum estate now also includes a holiday park.
The castle is split into three separate properties, consisting of the original tower keep, and separate Georgian and Victorian wings, each with their own style.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
