Londoners and London-lovers: please suggest some (non-obvious) cool things in London to do in March. (I’m insisting on lots of time at the British Museum, and on the Mithraeum, and my wife wants the Harry Potter tour). I’ve been there, wife and daughter have not, son is going to school there.
@Popehat find out if there are any concerts at St. Martin's in the Fields (just off Trafalgar Square), and/or a musical service at St. Paul's. I'm not Christian, just interested in music and great acoustics, and both of these spaces are great spots to hear music.
@Plumbert @Popehat St. Martins absolutely, especially "X by candlelight", where X is a well-known classical piece. March 4 is Vivaldi, March 11 Magnificat, and March 24 is Moonlight Sonata. https://www.stmartin-in-the-fields.org/spring/
