An overview of the wartime aerial photographs which have been put into the inventory up to October 2004 and a detail of the area around Ypres.

At first an inventory was made of the "normal" archaeological heritage (e.g. prehistoric, roman, mediaeval remains). In a next phase trenchmaps were used to locate the World War One remains. Locating the huge amount of structures on modern maps proved to be time-consuming but enlightening. Even though the trenchmaps did not seem to be accurate enough to make a precise and detailed inventory, this study gave us a great deal of information and filled in some important gaps in the inventory. As I will explain more precise results were obtained by using other methods…
Because there is a huge amount of World War One remains in Flanders, the C.A.I. first decided to prioritise its work and make an initial inventory of the most seriously threatened areas. Several techniques had to be tried out and a unique opportunity came with the A19 Project, the first big scale 'battlefield archaeology' project in Flanders.
But meanwhile, a new project started in february 2004 to make an inventory of all World War I archaeological in Western Flanders.
