Totnes Castle in Devon forms one of the Shell Keeps in Devon and Cornwall. The castle was placed in State Guardianship in 1947, and S.E. Rigold wrote the first MPBW pamphlet guide in 1952. This continued as the DOE pamphlet guide (1979) [8 pp.; price 5p] with the blue header making a reference to the fuller ‘blue guides’ available at other sites.
This was expanded, with very slightly adapted text as an English Heritage guide (1983; 2nd ed. 1990 [30p]). It doubled in length and included black and white photographs, a single page plan, and a reconstruction by Alan Sorrell. The description now preceded the history.
