10 Complex Wlodarz - the complex is located near the village of Walim, inside Włodarz Mountain 50°42′8″N 16°25′4″E. There are four entrances 80 m - 160 m away from each other leading to tunnels (180 m - 240 m long) containing guardrooms. The entire complex is a large amount of corridors intersecting at right angles and forming a grid. It contains one of the biggest unfinished halls (10 m high). There is a shaft leading to the surface (depth 40 m, diameter 4 m).[16] Some of the corridors have higher second levels connected by small shafts (depth 3 m - 5 m, diameter 1.5 m). This is a stage of creating big halls. Two tunnels were bored, one over the other and then the ceiling was collapsed to create a large space. Approximately 30% of the complex is flooded and can only be accessed by boat. The total length of the tunnels is 3,100 m
