A tent festival in the Stadtpark Teichwiesen at Wolfhagen, west of Kassel, held over some twelve days at the turn of May and June; it has run since the mid-1990s and reached its thirtieth edition in 2025. The tent takes up to 2,200. Pop, rock, jazz, cabaret and comedy share the bill — Ronan Keating, Gotthard, Matthias Reim, Nils Landgren, the Quatsch Comedy Club. The non-profit company behind it, registered at Kassel, is run from Burgstrasse in Wolfhagen.
