Cairnbulg Castle, Medieval castle in Rathen, Aberdeenshire, Scotland.
Cairnbulg Castle is a medieval castle in Rathen, Aberdeenshire, built as a central tower house with an attached wing and a round tower at its southeastern corner. The stone structure reflects the defensive design typical of 16th-century Scottish fortified homes.
The castle was originally called Philorth and belonged to the Comyn family until Robert the Bruce granted it to John Ross in 1306. This transfer marked a turning point, linking the property to prominent figures in Scottish history.
The interior displays family portraits showing every laird since 1570, which document the Fraser family line across centuries.
The castle remains a private residence owned by the Fraser family and can only be visited by prior appointment. You should arrange your visit in advance to ensure access.
The castle sits on a raised platform surrounded by remains of a water-filled moat that stayed active until the 1900s. This water system served as a key defensive feature for the medieval fortress.
