In Strathdon in Aberdeenshire, on a promontory above the River Don, the ruins of one of the greatest medieval castles in Scotland spread across a considerable area of ground. Kildrummy Castle is not well known to the casual visitor — it sits well off the main tourist routes, requires a specific detour to reach, and lacks the clifftop drama of Dunnottar or the fairytale silhouette of Craigievar. But for anyone seriously interested in Scottish medieval architecture and the history of the Wars of Independence, Kildrummy is essential. It was one of the most sophisticated castle designs in fourteenth-century Scotland, its builders were aware of the latest developments in castle architecture from France and Wales, and its history encompasses some of the most dramatic episodes of the independence wars.
What is Kildrummy Castle and where is it?
Kildrummy Castle is a ruined thirteenth and fourteenth-century courtyard castle in Strathdon, Aberdeenshire, Scotland, managed by Historic Environment Scotland and open to the public. It sits on a promontory above the River Don about 10 miles west of Alford, in the heart of the Aberdeenshire uplands. The surviving ruins include the remains of a great gatehouse, four round towers of varying sizes, the original curtain wall, and the foundations of the great hall and chapel. The castle was never substantially rebuilt after its final abandonment in the eighteenth century, and the ruins give a clear impression of the original medieval design.
Which clan held Kildrummy Castle?
Kildrummy Castle was most closely associated with the earldom of Mar — one of the oldest and most significant earldoms in Scotland. Clan Mar held the earldom and the castle from the thirteenth century, and the castle's history is bound up with the political fortunes of the Mar earls across two centuries of Scottish history. The castle also had significant associations with the Bruce family during the Wars of Independence — it served as a refuge and stronghold for Bruce's supporters at crucial moments in the conflict.
How old is Kildrummy Castle?
The castle was built in the late thirteenth century — probably between 1250 and 1290 — making it approximately 730–775 years old. The builder is thought to have been Gilbert de Moravia, Bishop of Caithness, acting under the authority of Alexander II or Alexander III of Scotland. The design shows awareness of the most advanced castle-building ideas of the period, including the great round towers and the twin-towered gatehouse that were being developed in Wales and France at the same time.
A key fact: the gatehouse modelled on Harlech
Kildrummy's most remarkable architectural feature is its great gatehouse — a twin-towered structure that is directly comparable to the gatehouses of Harlech and Beaumaris castles in Wales, built by Edward I's master builder James of St George. The similarity is so close that Edward I himself is thought to have ordered improvements to Kildrummy's gatehouse during his occupation of the castle in the 1290s — bringing Scottish military architecture into line with the most advanced thinking in the English royal building programme. The result is a gatehouse that is essentially a Welsh concentric castle element transplanted into a Scottish Highland setting, giving Kildrummy a unique position in the history of British medieval fortification.
The Wars of Independence — siege and betrayal
Kildrummy's most dramatic historical episode came in 1306, in the immediate aftermath of Robert the Bruce's bid for the Scottish kingship. With English forces pressing from the south and many Scottish nobles hostile to Bruce, his queen Elizabeth de Burgh, his daughter Marjorie, and his sister Mary were sent north to Kildrummy for safety under the protection of his brother Nigel Bruce. An English army under the Prince of Wales besieged the castle, and after a sustained defence the castle fell — through treachery rather than assault. A blacksmith named Osbourne, bribed with as much gold as he could carry, started a fire that destroyed the castle's grain stores and forced surrender. Nigel Bruce was captured and executed. The queen and the other women were captured and imprisoned. Osbourne received his promised gold — poured molten down his throat, according to tradition, by the English commander. The episode captures both the desperate nature of the early Bruce campaign and the brutal world in which it was fought.
The Jacobite rising of 1715
Kildrummy Castle had one final significant historical episode — its use as a base by John Erskine, Earl of Mar, who launched the Jacobite rising of 1715 from the castle. Mar raised the standard for James Francis Edward Stuart (the Old Pretender) at Braemar in August 1715, and the rising that followed — known as the Fifteen — was the most serious Jacobite challenge to the Hanoverian succession before the Forty-Five of 1745. The rising ultimately failed, and Mar fled to France. The castle was partially demolished after the rising to prevent further use as a Jacobite stronghold, and it was never again habitable.
The architecture of Kildrummy
Even in ruin, Kildrummy's architectural quality is apparent. The curtain wall originally enclosed an approximately oval courtyard with four round towers and the great gatehouse — a sophisticated design that minimised blind spots and provided overlapping fields of fire. The great hall and chapel within the courtyard were substantial buildings whose foundations survive. The snow tower — the largest of the round towers, which contained the well — stands to a considerable height and gives the clearest impression of the original scale of the fortifications. The overall plan reflects a serious engagement with the problem of how to defend a promontory site using the most advanced military architectural thinking of the late thirteenth century.
