Achallader Castle

Achallader Castle is a 16th-century tower house in Argyll and Bute with two standing walls beside Loch Tulla. The stone structure shows traces of corbelling and sits among farm buildings at Achallader Farm.

Sir Duncan Campbell of Glen Orchy took control of the castle in 1587 following disputes with rival families over local lands. Later, the structure suffered damage when the MacGregors set fire to it in 1603, and further harm came afterward.

The castle served as a meeting point where Highland leaders gathered to discuss regional matters and make important decisions together. Today, visitors can sense the historical importance of this place that once brought together influential local figures.

The ruins are visible from the road and from railway lines when traveling north from Bridge of Orchy toward Fort William. Visitors should know that access is via private farm land and it is worth checking whether a visit is possible before arriving.

Despite multiple destructive events over the centuries, two walls of the castle remained standing and today form a distinctive landmark in the flat landscape. These remains hint at the original building method and the lasting quality of the stone construction.
