In 1937, in the preparations for war of Nazi expansion, Hoesch AG forced Borussia Dortmund to leave Weiße Wiese and relocate to Stadion Rote Erde, south of downtown. The sports field eventually gave way to a swimming pool at the newly built Hoeschpark, which, however, was not built until 1951 as Stockheide Swimming Pool. A commemorative plaque was erected there for the historic location.
