I’ve never before been into Grosvenor Chapel, the parish church of Mayfair next door to Harry’s Bar.   It’s quite sweet, rather like a parish church in New England, commissioned by Sir Richard Grosvenor in April 1730, possibly designed from a pattern book by its builder, Benjamin Timbrell, who had worked with Gibbs on the Oxford Chapel.   It cost £4,000.   The spiral volutes were added by William Skeat during repairs in 1829 and the chancel was poshed up just before the first world war by Ninian Comper:-
