Wigmore Hall, built in 1901 as a piano showroom, is one of the best and most active classical-music venues in town, with more than 460 concerts a year. This isn't just because of its fantastic acoustics, beautiful Arts and Crafts–style cupola over the stage and great variety of concerts, but also because of the sheer quality of the performances.
The Sunday morning concerts at 11.30am (which are followed by coffee or sherry) and the lunchtime events at 1pm on Mondays (broadcast live on BBC Radio 3), are excellent value (adult/concession £16/14).
