The Poseidon system, which is the pseudokarst system that was developed in sandstones in NE Bohemia, is described. The fissure labyrinths, abysses, and block accumulations can be found in an area of approx. 26,800 m2. The total length of the man-accessible underground spaces of the Poseidon system is at least 27.5 km. The vertical range amounts 105 m. Thanks to its enormous dimensions, the Poseidon system is able to store an inside cold microclimate. This cold microclimate supports the occurrence of cold adapted plants and invertebrate animals, five glacial relicts (four spiders and one mite) included. By its structure, microclimate and communities of cold adapted organisms, the Poseidon system represents an important object in speleology, geomorphology, biology, and nature conservation.
