Kozje stene are sharp ridge in the north Jadovnik, whose north-eastern side plunges into the Samokovska River valley, above which very attractive rocks rise and by which the preserve is named. Large venture through Kozje stene made Dragoljub Mijatovic who conducted water through huge rocks from the top of Kopaonik, over precipices and steep cliffs with the system of channels and devices for irrigation. He began the work in 1927, and the direction and the slope was traced using an improvised device for elevation. Despite the disbelief of most locals and the then experts, on August 14, 1928 in village Žutica, to his farm, water arrived. Channel, 18 km long, was used until 1949.
