The shopping mall and park exists on the former land owned by the steel manufacturer Thyssen.
CentrO.Park was built adjacent the CentrO. shopping center and was a free entry / pay per ride park. In 2001 the park was taken over by German showman Oscar Bruch Jr. After the 2010 season, Bruch sold the park to Merlin Entertainments. Merlin operated the park for the 2011 season as CentrO. Park. The park did not operate during the 2012 season while it was transformed into the Sea Life Abenteuer Park. The new park was part of and entered via the adjacent Merlin owned Sea Life Centre. In 2014, the Sea Life Centre connection was discontinued and a few rides were added. After the 2015 season the amusement rides were removed and the park returned to being free public park as it was originally.
