Moy Castle
Moy Castle stands as a remarkable example of a 15th-century Scottish tower house located on the Isle of Mull, Scotland. Perched on a rocky outcrop near Lochbuie, this hill castle was the hereditary stronghold of the Clan Maclean of Lochbuie. Its strategic position and robust construction highlight the defensive and residential needs of Scottish clans during the late medieval period.
The castle was initially built in the early 15th century by John Maclean, the third Laird of Lochbuie, and completed by his son, Hector Reaganach Maclean, the fourth Laird. The lands were granted to Hector Reaganach Maclean in 1360, marking the beginning of the Macleans' tenure in the area. Moy Castle's first documented mention appears in a royal charter from 1494, confirming ownership under the Lord of the Isles. Over the centuries, the castle witnessed significant historical events, including clan conflicts and political upheavals.
Architectural features and layout
The castle is a classic Scottish tower house with a nearly square footprint measuring about 10.7 meters on each side and rising to approximately 17.5 meters high. It comprises three main floors plus a garret, which is a small attic space beneath the roof. The walls are constructed of local stone and stand largely intact to the gables, showcasing the durability of medieval masonry techniques.
One of the castle's most notable defensive features is its crenellated parapet, a battlemented wall at the top of the tower designed for protection during attacks. Two cap-houses sit atop the tower, providing access to the roof and serving as lookout points. Surrounding the castle on the northwest side are the remains of a rocky ditch, which functioned as a natural defensive barrier against invaders.
Internally, the castle's ground floor contains a freshwater well approximately 1.8 meters deep, an unusual and vital feature that ensured a reliable water supply during sieges. Adjacent to the southeast side of the tower was a barmkin, a small enclosed courtyard used for protecting livestock and storing supplies during times of conflict.
Historical context and clan significance
Moy Castle served as the principal seat of the Macleans of Lochbuie, a branch of the powerful Clan Maclean. The castle's history is deeply intertwined with the turbulent clan rivalries and political dynamics of the Scottish Highlands. In the late 17th century, the castle was briefly seized by the Clan Campbell during the Jacobite uprising of 1689, reflecting the shifting allegiances and power struggles of the period.
Despite these conflicts, control of the castle was eventually restored to the Macleans. However, by 1752, the family abandoned Moy Castle in favor of the more modern Lochbuie House, signaling the end of the castle's use as a residence.

Later history and cultural legacy
After its abandonment, Moy Castle gradually fell into ruin but retained cultural significance. It gained literary fame when the renowned writers Samuel Johnson and James Boswell visited in 1773 during their famous tour of the Hebrides. The castle also appeared in the 1945 British film I Know Where I’m Going!, further cementing its place in popular culture.
In the 21st century, Moy Castle has been the focus of extensive preservation efforts. Conservation work conducted between 2006 and 2015 stabilized the structure, preventing further decay and allowing visitors to appreciate this well-preserved example of late medieval Scottish fortification. Today, it stands as a testament to the architectural ingenuity and historical legacy of the Scottish clans.
Architectural details and defensive features
The castle’s stone walls are notable for their thickness and the skillful masonry typical of the period. The crenellated parapet provided defenders with cover while allowing them to repel attackers. The cap-houses not only facilitated access to the roof but also enhanced the castle’s defensive capabilities by serving as vantage points.
The location on a natural rocky platform adds to the castle’s defensibility, making direct assault difficult. The remnants of the rocky ditch on the northwest side further enhanced this natural defense by creating an obstacle for any approaching forces.
Interior features
The interior layout was practical for both defense and daily living. The ground floor well was an essential feature, ensuring a secure water supply during sieges. The upper floors would have contained living quarters, storage rooms, and possibly a great hall for gatherings and clan meetings. The garret offered additional space, likely used for storage or as a lookout post.
