What Happened To Kilchurn Castle?

Ask any photographer where to catch Scotland’s most reflected castle and they’ll point you to the head of Loch Awe. Kilchurn Castle sits there roofless and windswept, mirrored in still water on a good morning, and it looks like it’s been waiting for someone to come home. In a way, it has been — for nearly three centuries, nobody has.

Land taken from the MacGregors

The story doesn’t start with the Campbells. The land Kilchurn stands on originally belonged to Clan Gregor before it passed to Colin Campbell around 1440. Duncan Campbell, 1st Lord Campbell, handed the lands of Glen Orchy to his son Colin to secure his loyalty after the sudden death of Colin’s elder brother, Gillespec — a very Campbell way of keeping a promising son close and a title in the family. The castle’s existence is first recorded in a charter dated March 1449, described as “apud Castrum de Glenurquhay” — at the Castle of Glenurquhay.

A tower house built for power, not just defence

Kilchurn began as a courtyard and a five-storey tower house, holding a hall, private chambers, a cellar and a prison. It sat on what was then a genuine island at the loch’s edge, reachable only by boat or a hidden, part-submerged causeway — a design that let the Campbells watch the water and control who came and went along one of the key routes into Argyll. 

Colin’s son Duncan, the 2nd Lord, added the laich hall to the courtyard before he was killed at the Battle of Flodden in 1513 — one of the darkest days in Scottish history, and a reminder that even a well-fortified Highland stronghold couldn’t shield its lairds from the battlefield. The castle kept growing over the following century: around 1614, Sir Duncan Campbell, 1st Baronet, rebuilt the south range and added a chapel within the courtyard, and earlier, the 6th Laird had added chambers and remodelled the parapets with the distinctive circular corner turrets you can still pick out today. 

The most powerful branch you’ve never quite heard of

Colin’s descendants, the Campbells of Glenorchy, became the most powerful junior branch of Clan Campbell, and Kilchurn remained their power base for around 150 years. At times they nearly rivalled the chiefs of Clan Campbell themselves, the Earls of Argyll, for influence. This is the bit that surprises visitors: Kilchurn wasn’t a satellite outpost of Inveraray, seat of the Duke of Argyll — it was the seat of a rival Campbell dynasty entirely, one that eventually out-titled its cousins by becoming Earls of Breadalbane. 

“Slippery John” and the barracks

The most colourful laird to call Kilchurn home was Sir John Campbell, 1st Earl of Breadalbane, nicknamed “Slippery John” for playing both government and Jacobite sides against each other and profiting handsomely from it. In 1689 he retired to Kilchurn and converted it into a garrison stronghold: the old tower house became officers’ accommodation, while a barracks for 200 men went up on the north side of the courtyard. That barracks block survives in remarkably good condition and is today the oldest surviving barracks on the British mainland — a quietly extraordinary claim for a ruin most people photograph and move on from. 

Despite the investment, the garrison saw little real action, serving mainly as an outpost for government troops during the Jacobite risings of 1715 and 1745. 

Abandoned, then struck by lightning

By 1740, the Campbells had shifted their main seat east to Balloch — later renamed Taymouth Castle — and Kilchurn’s days as a lived-in home were effectively over. They tried and failed to sell Kilchurn to the government, and the castle was left to the elements. In 1760 it was badly damaged by lightning and completely abandoned; a turret still lies upside down in the centre of the courtyard today, physical proof of just how violent that storm was. Locals then quietly helped themselves to its stone for other buildings — the fate of many a Highland ruin. 

Sometime in the 19th century, drainage works lowered the level of Loch Awe, and Kilchurn’s island became the peninsula you can walk to today without getting your feet wet.

A ruin that inspired poets and painters

By the early 1800s, Kilchurn had already become a romantic icon. J.M.W. Turner painted the castle in his 1802 watercolour “Midday,” capturing it amid the wild weather and geology of Argyll, and William Wordsworth was moved enough by the ruin to write it into verse the following year. Two centuries on, it’s one of the most photographed castles in the country, particularly on a still morning when Loch Awe turns to glass. 

Kilchurn Castle: the essentials for visiting

• Where: At the northeastern end of Loch Awe, near the village of Lochawe, Argyll and Bute — about two miles west of Dalmally, just off the A85.
• Getting there: Drive to the car park at the northern end of Loch Awe on the A85, then walk in under the old railway viaduct — allow a couple of hours to explore the grounds properly. In summer, you can also arrive by boat from Lochawe pier, which is arguably the more atmospheric route in.
• Current access: The castle is cared for by Historic Environment Scotland and can be viewed year-round from the outside. The interior is currently closed for conservation work, with protective fencing around the tower, but the grounds and exterior views remain well worth the walk.
• Good to combine with: Dunstaffnage Castle and Castle Stalker are both within reach for the same day out — though Castle Stalker needs booking well in advance if you want to go inside.
• Best photo conditions: Early morning, when the loch is still and the reflection is at its sharpest, with Ben Cruachan rising behind.

“It’s a far cry to Loch Awe,” goes the old Gaelic proverb — and Kilchurn, isolated at the water’s edge with the hills of Argyll behind it, still feels every mile of that distance.

So — what happened to Kilchurn Castle? No siege, no dramatic clan battle at its gates. Just a slow shift of power eastward, a family that outgrew its old seat, and one furious storm that finished what neglect had started. It’s a very Highland kind of ending: not defeat, just time.

Have you stood at that famous viewpoint across the loch, or walked in under the viaduct yourself? We’d love to hear which castle on Loch Awe stole your heart.
