Rudolf Kögler laid out this probably unique geological relief map (including the surrounding rock garden) in his own garden between 1931 and 1937. The map shows the region around the neighboring Vlčí Hora (Wolfsberg) in relief on approx. 50 m², consisting of the rocks occurring in each of the locations shown.
Rudolf Kögler was actually a textile designer, but primarily an amateur natural scientist. In addition to the relief map, he also laid out the first nature trail in Bohemia in 1941, which begins very close by. Today a granddaughter of Rudolf Kögler leads through the relief garden.
