Lochranza Castle

Robert the Bruce is said to have landed at Lochranza from Ireland in 1306 at the start of his long struggle to liberate Scotland. The castle was certainly in the possession of his grandson when he became King Robert II of Scotland in 1371.
It subsequently saw use as a royal hunting lodge. Several further changes of ownership followed, during which the castle slowly became transformed into the tower house we see today. It was also gradually turned to face towards the village rather than the sea.

During the 1490's it was used as a base from which James IV could attack the MacDonalds, the Lords of the Isles. 1614 saw its occupation by James VI; and Cromwell occupied it in the 1650's. Then, following the foreclosure of a mortgage, it found its way in 1705 into the hands of the Hamiltons, like so much else in Arran. It has been disused since the end of the 18th Century.
