Comlongon Castle was built to combat the frequent border incursions by English raiders. An early mention of the castle is that in 1331 the Earl of Moray, Thomas Randolph, gave the property to his nephew, Sir William Murray. The Keep has stood witness to generations of violent border disputes between the several powerful border families that hail from this region.

Early in the 18th Century the descendants of the Murray's, Lord Mansfield of Scone Palace, Perthshire, had a Mansion House built adjacent to the Keep but probably rarely lived in it. It is believed that much of the stone required came from the ancient walls and outbuildings, which by then had lapsed into a state of dilapidation. The first mansion was partly destroyed by a fire in the late 19th Century and was rebuilt in 1901.

Today guests are welcomed to stay and dine in this fabulous 14th century castle. With its massive walls, forbidding dungeons and spiral stone staircases the castle offers guests a unique and memorable experience.
