On Verdun Street, you may visit the National Necropolis of World War One Prisoners. French soldiers and captured civilians lay here: they perished in German camps. This graveyard was inaugurated on September 12th 1926 (with 13298 graves and 2 ossuaries). Fredy Stoll was a prisoner in Graffenwohr, Bavaria. With the help of his fellow prisoners, he sculpted a landmark out of a granite block: you may see this sculpture at the end of the central alley.
The site has been a UNESCO World Heritage Site since 2023.
