In 1940 a network of defences was hastily built all over the British Isles to prevent an anticipated German invasion. Sited at road junctions, canals and other strategic points these constructions were called "pillboxes". Despite the passage of time many of these remain as permanent monuments and a silent tribute to the courage and tenacity of the British people in the dark days of 1940. This large format photo book records some of what remains today. Click here to view The Full Colour Premium Edition. For further information visit The Pillboxesuk Website at www.pillboxesuk.co.uk
