Kassel-Calden Circuit
Kassel-Calden Circuit was a former airfield circuit located on the Kassel Airport in Kassel, Hesse, Germany.
The circuit was opened in August 1971 for the venue of ADAC Hessenpreis due to the expensive costs of hiring Hockenheimring for this event. Besides national championships, the circuit also hosted races for some international championships, such as FIA European Formula 3 Championship and Interserie.
