After the war the American occupying forces held jazz concerts at the arena, and in 1947 used it for an Easter service which they invited Germans to attend. As early as 1946 a sports meeting was held there. In 1945 it was renamed Heiligenberg-Anlage (Heiligenberg facility), but usage gradually returned to the original name of Thingstätte. The site is now municipal property, has been declared a state protected monument, and like the rest of the mountain, is tended by the Schutzgemeinschaft Heiligenberg.
