During the Second World War hundreds of miles of British coastline was fortified in response to the threat of German invasion. The physical remains of these defences are now considered an important part of our archaeological heritage, yet it can often be difficult to visualise their impact upon the landscape. The computer reconstructions on this website aim to recreate the defence landscape in and around Walberswick in Suffolk, one of many places fortified during the invasion scare of 1940. The reconstructions are based on a detailed historical and archaeological investigation involving field survey, analysis of original documents, aerial photographs and interviews with eyewitnesses who experienced the defences at first hand. The first video introduces the elements that made up the defences in and around Walberswick. Three further videos explore the fortifications in greater detail.
