"The book is lavishly and beautifully illustrated with photographs of the fortifications, original drawings and sketch maps of the military works and historical military geology maps. Many examples of the German fortifications, particularly tunnels and observation posts, survive in the landscape today and some have been adapted for modern use, such as museums." (Judy Ehlen, Geoscientist, geolsoc.org.uk, 2020)
