Sir Charles Peers, the Chief Inspector of Ancient Monuments, prepared two Office of Works guidebooks in 1917: Kirby Muxloe Castle in Leicestershire and St Botolph’s Priory in Colchester. (Simon Thurley, Men from the Ministry, p. 156, only notes Kirby Muxloe’s guide.) The guide to the priory was re-issued in 1964 by the Ministry of Public Buildings and Works [Worldcat]. The 1964 edition consists of 12 pages divided into two sections: History (pp. 3-6) and The Priory Buildings (pp. 7-12). There are two black and white photographs and a partial plan of the priory as a centre double page spread. Peers makes a reference to the Victoria County History for Essex (1903) for his list of priors.
The guide to St Botolph’s Priory is no longer available, although there is a useful section with plan and reconstruction in Philip Crummy’s City of Victory: the Story of Colchester – Britain’s First Roman Town (1997). However Kirby Muxloe Castle is covered in a joint English Heritage guidebook (by John Goodall) with Ashby de la Zouch Castle.
