Sparebanken Sor Arena ("South Arena") is a football stadium located at Torsvika in Kristiansand, Norway. The all-seater has a capacity of 14,563 people, and serves as the home ground of Tippeligaen side IK Start. It was designed by Kjell Kosberg, and is architecturally similar to Aker Stadion. The venue has seen concerts by Elton John, Dolly Parton and A-ha, among others. UEFA refers to the stadium as Kristiansand Arena.
Construction started in 2006, and the stadium opened on 15 April 2007, replacing Kristiansand Stadion as Start's home ground. The venue cost 400 million Norwegian krone (NOK), of which the stadium itself cost NOK 250 million, after significant cost overruns. While originally planned with artificial turf, the venue was ultimately built with a natural grass pitch. The venue and the holding company Start Stadion were taken over by Sparebanken Sor, the main creditor, in 2008. They subsequently also took over Start Toppfotball, the company running the club. Both companies were sold to Ernst Ravnaas in 2009. Following decreased attendance, ahead of the 2011 season the seating on the corners was sold as advertisement space and the maximum capacity has artificially been reduced to 11,700.
