The Cristal Arena is a multi-purpose stadium in Genk, Belgium. It is currently used mostly for football matches and is the home ground of Racing Genk. The stadium holds 25,000 (of which 4,200 are standing places) and was built in 1999. Heusden-Zolder used to play at this stadium for their single season at the top level in 2003-04. Following the relegation of the club, it moved to Mijnstadion in Beringen. The average home attendance varies from 20 000 to 22 000 supporters who visit the stadium every fortnight.
Before the start of the 2007-2008 season, the stadium was known as "het Fenixstadion". However, early 2007 Racing Genk signed an agreement with the Alken-Maes brewery to lease the name of the stadium for a 5 year period.
