The Winterberg tunnel was built by the Imperial German Army through a ridge near Craonne, France during World War I. The 300 m (980 ft) underground passageway, which connected the German frontline to its rear echelon areas, was used to mitigate French artillery on this part of the line when moving troops and equipment into trenches. It was built at a depth of more than 20 m (66 ft). In 1917, more than 250 German soldiers were buried alive when the French launched a targeted barrage at both ends of the Winterberg tunnel. Only three men survived. No rescue attempt was launched due to continuing shelling of the area and a subsequent French counterattack. The tunnel was largely forgotten until a family of amateur historians announced they had found one of the tunnel's entrances in 2020.
