 Every year in the Benedictine ruins of the Monastery of St. Peter und Paul the theatre festival "Calwer Klostersommer in Hirsau" (Calw Monastery Summer in Hirsau) takes place.This replaced the Klosterspiele Hirsau (Monastery Plays of Hirsau), which were rich in tradition.Hermann Hesse's Gerbersau stories provide the material for the yearly "Gerbersauer Lesesommer“ (Gerbersau Reading Summer).
