Côte 108 Berry-au-Bac, Military memorial site in Berry-au-Bac, France
Côte 108 Berry-au-Bac is a battlefield memorial in northern France marked by a large crater from World War I mining operations. The depression was created by explosive detonations and is surrounded by preserved trench systems and underground passages that remain visible today.
The hill was a key battleground during World War I where French and German troops dug extensive underground mines against each other. On June 23, 1915, French forces detonated a major explosion that permanently transformed the landscape.
The site speaks to underground combat methods used during the war, with preserved tunnel systems and trenches that show how soldiers fought beneath the surface.
The grounds can be explored through guided tours organized by the nearby Dragon's Cave Museum. Pathways are clearly marked on the former military site and information panels explain what you are seeing.
This site preserves one of France's largest crater holes from a mine explosion, a detail that many war history visitors overlook. The crater offers a direct connection to underground warfare that is often forgotten in popular accounts of the conflict.
