As early as in 1866 ski jumping competitions were already organized in downtown Christiania, Oslo. To secure good snow conditions, the competition moved to a nearby hill called Holmenkollen, where the first jumps at the "Holmenkollrennet" took place on 31st January 1892 with well over 10.000 spectators present. Since then, the world's skiing elite meets at Holmenkollen every year, and the 50,000 spectators turn it into an annual celebration. Holmenkollen has held the World Championships in 1930, 1952, 1966 and 1982, and the Winter Olympic Games in 1952, when 101,400 people paid to watch the jumping and another 40,000 packed the viewpoint of the Gratishaug Hill. An Olympic spectator record! Originally, the Holmenkollen ski jump was made from tree branches and sprigs that had been covered by snow, and the longest jump was 21,5 meters. Since then, the jump has been rebuilt over 15 times in total. Today, the longest jump is 110.5 meters.
