The Regenwurmlager, which literally means Camp Earthworm, is an extensive underground fortification area constructed by Germany in 1920s-1940s, now in western Poland, near the city of Międzyrzecz. It was a system of underground bunkers interconnected by tunnels and corridors of total length over 100 km. In 1945 it was abandoned by the German troops retreating without significant fights.
