1943 construction started.
1944/5 construction ended unfinished at the end of World War II.


The underground structure named Unternehmen Riese (Project Giant) includes seven undergound structures in the Góry Sowie (Owl Mountains) of former Niederschlesien (Lower Silesia). The construction was started by the Third Reich Germany in 1943 and at the end of 1944 when the Red Army came close they were abandoned, still unfinished. Most likely is the intended use as an underground factory for war production. Some say it was intended as an hideout for Hitler, a Führerhauptquartier similar to the Wolfsschanze bunker. And there is a chance that it was intended for the construction of a super weapon, especially the atomic bomb. Some even guessed it could be the location of the lost Bernsteinzimmer, the amber room.

At the moment three of the seven underground factories are open for the public, at Rzeczka, Osówka and Walim. At the village Walim is the centre of the whole structure, the Kompleks Rzeczka (Rzeczka Complex) with a museum and the above mentioned exhibitions. It is the ideal starting point for visiting the underground structures.
