Kildrummy and Glenbuchat castles are close to each other in Aberdeenshire. The Ministry guidebook was prepared by W. Douglas Simpson in 1957. Simpson had prepared a series of studies on Kildrummy from 1923 to 1937. The guidebook is separated into two parts, leading with Kildrummy; each contains a section on the history and a description of the two castles. A set of black and white photographs of the two castles, and a plan of Kildrummy appear as a block in the centre of the guide; a fold-out plan of Glenbuchat appears at the end.
