Thingstatte
About
A Thingspiel (plural Thingspiele) was a kind of multi-disciplinary outdoor theatre which enjoyed brief popularity in pre-war Nazi Germany during the 1930s. A Thingplatz or Thingstätte was a specially-constructed outdoor amphitheatre built for such performances. About 400 were planned, but only about 40 were built between 1933 and 1939.
