While the Western Front of the Great (or First World) War is deeply engrained in the European historical consciousness, memories of the Eastern Front are less prominent. Here, events have been repressed, obscured by the subsequent experience of the Second World War and by heritage policy in the region. The authors present the results of archaeological investigations of a battlefield in central Poland, where static trench warfare was fought between December 1914 and July 1915. A unique landscape palimpsest was formed, the present neglected state of which is a material expression of contemporary attitudes to the legacy of the forgotten Eastern Front. The study illustrates the wider intersection of warfare, identity and memory.
