Ruins of Tarbert Castle (photograph by Chris Downer)

Menstrie ‘Castle’ – home to the Alexanders of Menstrie, whose descendants included the Earls of Stirling and probably the Irish Earls of Caledon. It now houses a museum and self-catering holiday accomodation.

Lochranza Castle, Isle of Arran (Ranald MacAlester was keeper of this castle c. 1460)

Torrisdale Castle, eastern Kintyre (built by Keith Macalister of Glenbarr in the early 1800s, Torrisdale is now owned by the unrelated Macalister-Hall family)
