This odd, mod building houses both the stadhuis (town hall) and the opera hall, aka Muziektheater, hence the name 'Stopera'. It opened in 1986. For a peek behind the scenes, take a guided tour (adult/child €6/5) on Saturdays at 12.15pm. The arcade between the town hall and the theatre has an intriguing display on NAP, Amsterdam's sea level measurements.

Free lunchtime concerts usually take place from 12.30pm to 1pm on Tuesdays from September to May; doors open at 12.15pm.
