Kildonan Castle

Kildonan Castle stands on the southern coast of the Isle of Arran, a small village named Kildonan. The castle sits on cliffs overlooking the Firth of Clyde and the island of Pladda. Built in the 13th century by the MacDonalds, it defended against attacks through the firth. The castle was later used as a hunting lodge by Scottish kings such as Robert III. In 1544, it passed to the Earls of Arran. The castle’s history reflects its strategic importance. The MacDonalds, Lords of the Isles, constructed it to control access to the firth. Robert III stayed there when the island was under royal control. The Earls of Arran took ownership in the 16th century, marking another chapter in its past. Visitors find the castle’s ruins on a dramatic cliffside setting. The views stretch across the Firth of Clyde to Pladda Island. The remains include sections of the original walls and foundations. The site offers a quiet spot to imagine its former role as both a fortress and a royal retreat.
