A complete artillery casement dating to 1938, comprising 5 structures linked by 2 km of underground tunnels.
The casement included an underground filtering plant, extensive ammunition stores, a machine room/power plant, and a wartime barracks 50 m below the ground surface.
The entire underground area is accessible, as are the K-S22a "Krok" entrance building, the K-S22 "Horymír" gun tower and the K-S21 "Kazi" and K-S24 "Libuše" infantry blockhouses.
