Schwetzingen Palace is a schloss in the German state of Baden-Württemberg. Schwetzingen was the summer residence of the Electors Palatine Charles III Philip and Charles IV Theodore (of the House of Wittelsbach). It is situated in Schwetzingen, roughly equidistant from the electors' seats at Heidelberg and Mannheim, and is most notable for its spacious and ornate gardens. Other than these exceptionally well preserved gardens and the palace proper, the compound also features the Schlosstheater Schwetzingen, the principal venue for the annual Schwetzingen Festival.
