The Great War (1914-1918) had an enormous impact on the landscape and can be seen as a cultural calamity. This event created a complete new landscape full of mud, craters and military structures. One hundred years later, after a spectacular reconstruction of the landscape, traces are still visible today. These are the last witnesses of an agitated period that lasted for four years long in our regions. The PhD-research of Hanne Van den Berghe is focused on the location and historical dimension of these relics in the province West-Flanders. The study takes place in three different regions with each another landscape type and warfare, namely the area around Newport, Ypres and Kemmel. A historical landscape characterisation is made, which goes from 1914 until today. The used sources for this characterisation are valuable historical aerial photographs taken during and after the war, originating from different archives. This material is processed using many different spatial analysis techniques. Next to the landscape characterisation, actors and processes are described that defined the reconstruction of the post-war landscape.
