Sadler’s Wells has been a part of the fabric of London life for so long (since 1683) that its current two-house home, dating to 1998, is actually the sixth. You can turn to this Islington establishment to catch some of the world’s greatest companies in movement- or rhythm-based performances that transcend language. Its specialties are ballet (Matthew Bourne is a frequent guest artist), contemporary dance, and opera (Rufus Wainwright’s Prima Donna premiered here). It also programs the Peacock Theatre on Portugal Street near the Holborn Tube.
