The Schwetzingen Festival (German: Schwetzinger Festspiele, now Schwetzinger SWR Festspiele) is an early summer festival of opera and other classical music presented each year from May to early June in Schwetzingen, Germany.
In 1952, the broadcaster Süddeutscher Rundfunk founded the festival in the Schwetzingen area. It is located in a beautiful 250-year-old palace and park, Schwetzingen Castle, near the famous city of Heidelberg. The main venue is the historic Schlosstheater Schwetzingen. Nowadays, the successor organization is the Südwestrundfunk (SWR) and it organises many international concerts and music theatre events every year.
