Demolition of Second World War defences commenced before the end of the war, when the risk of Nazi invasion had diminished, and until recent years the study and recording of buildings and structures associated with twentieth-century defences has received relatively little attention. Despite the extent of the demolition work many examples of defence installations and structures survive throughout Great Britain. As Warwickshire was not as heavily defended as counties with coastal regions and those on the eastern side of Great Britain there are inevitably fewer examples of defence structures than in these kinds of areas. However, within Warwickshire a wide variety of defence buildings and structures still survive. This guide includes pill boxes, bombing decoy sites, anti-aircraft defences, air-raid shelters, army buildings, and Cold War defences. Complementing his study with photographs and maps, including suggested walks, Steve Carvell has compiled a detailed and important record of these often overlooked structures and defences across Warwickshire.
