Corgarff Castle is located at Corgarff, in Aberdeenshire. The castle was built in the mid-16th century by the Forbes of Towie. In 1571 it was burned by their enemy, Adam Gordon of Auchindoun, resulting in the deaths of Lady Forbes, her children, and numerous others, and giving rise to the ballad Edom o Gordon. After the Jacobite risings of the 18th century, it was rebuilt as a barracks and a detachment of government troops were stationed there, on the military road from Braemar Castleto Fort George, Inverness.
Military use continued as late as 1831, after which the tower served as a distillery and housed local workers. It remained part of the Delnadamph estate belonging to the Stockdale family until they passed the castle into state care in 1961 and gave the ownership of the castle to the Lonach Highland and Friendly Society. It is now in the care of Historic Scotland and is open to the public.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
