The Holmenkollen ski jump in Oslo, Norway. There have been ski competitions here since 1892. The hill has been rebuilt 19 times; important upgrades include a stone take-off in 1910, an in-run superstructure in 1914, and a new superstructure in 1928. During the Second World War, the venue was used as a military installation, but upgraded in the late 1940s. Further expansions were made ahead of the 1966 and 1982 World Championships, as well as in 1991. Between 2008 and 2010, the entire structure was demolished and rebuilt. As of February 8, 2011, the hill record is unofficially held by Anders Jacobsen at 142.5 meters. The official hill record was set March 5, 2011 by Andreas Kofler at 141 meters.
