Every summer Zurich's radio station rundfunk.fm occupies the courtyard of the National Museum for six weeks. The station specialises in mostly electronic tunes, so the centre of this summer festival is the Danspaleis, where you can, of course, shake your booty. The bars and food stalls help to create a fun atmosphere, which is especially good on a balmy night. Open daily 17:00 - 24:00.
