A total of 19 "Alla hopp! complexes" are to be built in the Rhine-Neckar metropolitan region with donations from the Dietmar Hopp Foundation. The opening ceremony for the fifteenth exercise and meeting place was held in Heidelberg, the birthplace of Dietmar Hopp, in October 2016. Four more complexes will follow in 2017. The Heidelberg complex is a landscaped park and boasts many sports and play areas fitted out with high-quality synthetic surfaces from Polytan.
