The Störtebeker Festival is an yearly open-air theatre festival in Germany. It is based on stories around the medieval German privateer Klaus Störtebeker and his Victual Brothers, who later turned to pirates.
Founded in 1959 as part of an East German cultural initiative, the festival has become Germany's most successful open-air theatre event, and is broadcast by public television network NDR. It is held in the small town of Ralswiek on the isle of Rügen.
