The English National Opera is celebrated for making opera modern and more accessible, as all productions are sung in English. It's based at the impressive London Coliseum, built in 1904 and lovingly restored a century later. The English National Ballet also holds regular performances at the Coliseum. Tickets range from £12 to £125.
Backstage tours of the London Coliseum are bookable online (adult/concession £10/£8).
