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. Background In 1959, the "Rügenfestspiele" were founded in Ralswiek as part of a cultural commission of the GDR and the Ralswiek natural stage was created. The place for the then Rügen Festival was found in the spring of 1959 between Ralswiek Castle and the Boddenufer, and the natural stage was then built in five months of construction and the village was converted into a festival venue. From 1959 to 1961 and 1980 to 1981 the Dramatic Ballad "Klaus Störtebeker" by Kurt Barthel was performed under the direction of Hanns Anselm Perten and the choral direction of Günther Wolf with about 1,000 participants. A total of 670,000 visitors were counted during these five summers. Production since 1993 Content In contrast to the piece of the time, the legend of the pirate Klaus Störtebeker, who sailed the Baltic Sea with his Vitalien brothers at the end of the 14th century, is told at the Störtebeker Festival since 1993, each spread over a period of four to six years. In 2006 the production was called In Henker's Hand, in which Klaus Störtebeker was beheaded. The fourth cycle is planned for the period 2007-2012; the first episode in the summer of 2007 was titled Betrayed and Sold. In 2009, a trilogy began about the treasure of Störtebeker. The cycle was completed by the piece Störtebeker's Death. In 2013 we started from scratch with the beginning of a legend. Sascha Gluth, who took over the role of Klaus Störtebeker from 2002 to 2012, was replaced by Bastian Semm. The role of Goedeke Michels was taken over by Andreas Euler. Both played their leading roles for a cycle long (2013-2017). Number of Visitors On August 17, 2007, the 912th performance since 1993 counted the four millionth visitor.
