Telenor Arena, formerly known as Fornebu Arena, is a multi-use indoor stadium located at Fornebu in Bærum, Norway. It will be used mostly for football matches and is the new home ground of the Norwegian Premier League side Stabæk, replacing Nadderud stadion which was used from 1961 to 2008. The stadium was opened ahead of the 2009 season. In June 2008, the telecommunications company Telenor acquired the naming rights to the stadium in a deal lasting until 2018. It is also referred to by supporters as Hangar'n (the Hangar).
In 1999 the club settled on Fornebu, the site of a large urban development project. Lengthy negotiations between the club, the municipality and the area's main developer came to an end in 2005 and the plans gained final approval on 21 June 2006. Demolition of existing structures on site began on 17 February 2007 and construction began shortly after. The project cost of NOK 585 million, of which 300 million was for the sports venue. Telenor Arena will be the venue for the Eurovision Song Contest 2010.
