The great spaces under Wiltshire in the old Bath stone mines are fascinating, and well worth the rare opportunities that exist to visit them. Monkton Farleigh was once open as a museum, but sadly no more. Having spent time working in one, this book covers some very familiar, and much unfamiliar territory for me. Admittedly, the spaces are not quite cities, but pretty substantial towns at least.
The history is interesting, the detail provided very satisfactory and the thought that such works would be simply unaffordable nowadays is quite telling.
Mr McCamley has done a fine job here, which should be interesting to all 20th century military historians, civil engineers and many others.
