The Heidelberg Thingstätte on the Heiligenberg is an example of National Socialist architecture and an open-air theater based on the model of ancient Greek theaters. The Thingstätte was built from 1934 to 1935 by the Reich Labor Service and Heidelberg students. The stage should primarily be used for propaganda events. But soon the National Socialists lost interest in the facility. During the Second World War the Thingstätte was largely unused. Today the Thingstätte is a cultural monument that is freely accessible to tourists, hikers and forest walkers. It has no structures and is neither fenced in nor illuminated.
