This antique style amphitheater was built on the saddle between Heiligenberg and Michaelsberg in 1935.
On the northern side of the river Neckar, on top of the Heiligenberg (Saints' Hill), sits an example of National Socialist architecture, embedded in the mountains forest. The Thingstaette was modeled after Greek amphitheaters and was built by State Labor Service and students at Heidelberg University from 1934 to 1935.
At its opening the theater was filled with 20,000 people, who listened to Joseph Goebbels' opening address. It was later abandoned and is now under monument protection. Despite it being hard to manage during events, several open-air concerts and opera performances are held there during warmer times.
