Re: NNG German Treasure Train

Not just a tunnel for passage through a mountain.

Before the tide of the war turned against the Germans after their 1943 defeat at Stalingrad, the Nazis built a massive network of tunnels and bunkers through the Owl Mountains that range southwest of Wroclaw — known as Breslau until the region was ceded to Poland after the war — to Walbrzych on the Czech border.

Some of the passages built in what the Germans called Project Riese, or Giant, have been opened to the public as historical exhibits but most remain unexplored and inaccessible due to postwar construction or cave-ins.
