Dundarg Castle

Dundarg Castle sits on a triangular plateau above sandstone cliffs rising about 20 feet (6 meters) over Aberdour Bay. The inner gatehouse, standing about 18 feet (5.5 meters) tall, is the most substantial surviving structure and reveals multiple archaeological layers from different periods.

The castle was built in the 13th century by the Comyn family and underwent reconstruction in 1334. It was later captured during a siege by Sir Andrew Moray, marking a significant shift in its control.

The name Dundarg comes from Gaelic words meaning red fort, referring to the distinctive color of the sandstone that was used to build it. This name choice reflects the reddish hues of the ruins that stand out against the surrounding cliffs.

The site sits on an exposed cliff edge, so visitors should be ready for uneven ground and steep drops nearby. Weatherproof clothing is wise, especially with the strong winds common along the coast.

The fortress forms part of the Nine Castles of Knuckle, a group of fortifications spread along the rocky headlands of North-East Aberdeenshire. This collection tells the story of a defensive line that once protected this coastal region.
