Góra Ostoia, Mountain summit in Lower Silesia, Poland.
Säuferhöhen is a mountain summit in the Sowie Mountains of Lower Silesia. The peak sits above an extensive network of concrete underground passages and chambers carved into the rock beneath the surface.
Construction of the underground complex began in 1943 for military purposes during World War II. The facility was developed within reinforced concrete structures at a strategic location in the occupied region.
The underground complex functions as an educational center, presenting exhibits and multimedia presentations about the wartime history of Lower Silesia.
Visitors can choose between different tour routes, including a standard route with lighting and a more challenging option through darker sections. Flashlights and sturdy footwear are helpful for exploration since passages are sometimes narrow and uneven.
Beneath the surface, boat passages and wooden walkways wind through northern corridors normally off limits to visitors. These waterways reveal how the underground facility used natural springs and created a sophisticated internal network.
