Formerly, its elite project FC Vestsjælland also used the stadium as its home ground.
The sports complex was built in 1927 by Slagelse Municipality, among others, as a result of the complete merging of Slagelse Boldklub and Slagelse Idræts-Forening to Slagelse B&I i 1919.

The stadium record of 10,000 spectators dates back to the early 1970s, when it hosted with a division match in Danish top tier between Slagelse B&I and Holbæk B&I.
