“Project Riese” is a code name for 7 underground structures built by Nazis during the World War II. Initially, their main purpose was to protect Germans' armament constructions from Allied air raids. According to some historians, they served as secret Headquarters for Adolf Hitler. Other claim that secret tunnels hid chemical and atomic laboratories.

Nevertheless, none of them were ever completed and their real purpose remains unknown. Some even say that what has been discovered in Owl Mountains Nazi complex is just a tiny piece of the whole Riese Project!

The seven complexes: River, Wlodarz, Osowka, Sokolec, Jugowice, Sobon, Jedlinka Palace and Gluszyca are located in Owl Mountains and Lower Silesia Region.

Work on the Riese project began in November 1945 and lasted for at least 18 months. It is estimated that around 13,000 prisoners (mostly from Auschwitz-Birkenau) took part  in the construction work.

Complex Wlodarz - It's the biggest and the youngest part of the Project consisting of 4 drifts large halls (up to 12 m) and a grid of tunnels (3200 m). It's partly flooded with water and its visitors can explore the complex's depths on boat.

Osowka - it's the most advanced Riese complex, often called the Underground City. It features an unique collection of numerous original objects from the WWII, a network of concrete corridors, reinforcements and halls including prominent "Casino" hall and Nazi Gold Train. Interactive exhibitions including holograms and sound effects, that one can found in Osowka, provide incredible visual experiences to all visitors.
