Loch Doon Castle was probably built in the late 1200s by an earl of Carrick – either Robert the Bruce or his father, also called Robert.
King Robert’s brother-in-law, Sir Christopher Seton, took refuge at the castle after defeat by the English at Methven in 1306.
The castle originally stood on an island in Loch Doon a flag marks the spot where it once was.
The entire castle was taken down, stone by stone, and re-erected on its present spot in 1935, in an effort to save the castle’s curtain wall as water levels rose due to the local hydroelectric scheme.
