Ardvreck Castle
Ardvreck Castle is a late 15th‑century rectangular stone keep standing on a rocky promontory in Loch Assynt, Sutherland. Built by the MacLeods of Assynt, it had a round stair turret corbelled to form upper rooms, vaulted lower floors and several gunports; the structure is now a ruin and a scheduled monument.

As it stood in 1650
What Ardvreck Castle looked like in its prime.
Perched on a rocky promontory in Loch Assynt, Ardvreck Castle was a rectangular four‑storey stone keep with a round stair tower at the south‑east angle. Upper floors were corbelled out to form square chambers with a small stair turret on the corbelling. The ground floor comprised three vaulted compartments; the first floor vaulted, the upper floors joisted. The fabric appears as rough grey and reddish‑brown rubble masonry with narrow slit windows and several gunports facing the loch.
Its story
The story of Ardvreck Castle.
The MacLeods of Assynt, c. 1490
Ardvreck was raised by the MacLeods of Assynt in the fifteenth century, about 1490, on a rocky promontory jutting into Loch Assynt in Sutherland. It replaced the older Assynt Castle, four miles to the north-west of Inchnadamph. The building itself was a simple rectangular keep, apparently of four floors, with a round staircase tower at the south-east angle corbelled out on the upper storeys to form square rooms, three vaulted compartments on the ground floor, and several gunports.
Montrose Handed Over, 1650
Ardvreck's place in Scottish history was fixed in 1650, when the royalist James Graham, 1st Marquess of Montrose, fleeing after his defeat at the Battle of Carbisdale, was handed over here to the Covenanter forces by MacLeod, Laird of Assynt. What actually happened is unclear, and two traditions survive. In one, MacLeod, loyal to the Covenanters, simply arrested the weary fugitive and held him. In the other, he gave Montrose comfortable shelter — and then betrayed him for a reward of £25,000.
The Mackenzie Capture and the Burning of Calda House
In 1672 Clan Mackenzie attacked and captured Ardvreck, and with the castle took control of the Assynt lands. In 1726 the Mackenzies built themselves a more modern manor house nearby, Calda House, named for the Calda burn beside which it stands — but a fire destroyed it in 1737. Castle and manor house were left as ruins, and both are protected today as scheduled monuments, Ardvreck holding that designation since 1936.
