With the commemoration of World War I (WWI) under way, a preliminary stocktaking can be made of archaeological research into the physical remains of this war. The question is to what extent the perspective on the study of WWI heritage, and consequently the way in which archaeological research into WWI remains has been conducted, has evolved over the last ten years. Are relics from WWI seen as a legitimate subject of inquiry or does its archaeology as a discipline still strive for recognition? This paper deals with the practices surrounding WWI archaeology in Flanders, Belgium, as well as the (methodological) problems concerning the study of WWI archaeological remains, based on the reports resulting from fieldwork carried out by professional archaeologists.
