FEATURES, ORIGIN, VALUES, LEGAL PROTECTION
The underground tourist route in Osówka complex  is a system of concrete corridors, halls of fortifications that were built on a large scale in 1943, by workers and prisoners from the camp Gross-Rosen. Excavations are part of "Riese" complex - Hitler's biggest quarters not only in Lower Silesia, but in the whole Reich. Osówka Complex is the most advanced facility in terms of  construction project in the Owl Mountains (Gory Sowie). The overground part of the complex is the external infrastructure of the underground premises. The largest two objects which attract the most attention are conventionally called "Casino" and "Gymnasium". "Casino" is a monolithic single-storey, reinforced concrete structure with a length of about 50 m and the second object, "Gimnasium" is a reinforced concrete foundation of technical premises designed to provide services to the underground part.  Today you can visit about 1700 m of underground corridors and halls, full of stories of the past years. It is the most interesting complex built in the Owl mountains (Gory Sowie).
Since 1996, it has been open to the public.
