Beauly Priory in Inverness-shire was a Valliscaulian foundation of 1230, by Sir John Bisset. The paper guide was prepared by William Douglas Simpson (1896-1968) in 1954; a second edition was published in 1978. The guide contains a short history followed by a description. A plan of the church is printed on the central pages.
Simpson served as university librarian for the University of Aberdeen (1926–66). He excavated at several castles in Scotland and write several Ministry guides (including Urquhart Castle).
