This parish church to the royal family is a delightful fusion of neoclassical and baroque styles. It was designed by James Gibbs, completed in 1726 and served as a model for many wooden churches in New England. The church is well known for its excellent classical music concerts, many by candlelight (£9 to 30), and its links to the Chinese community (with services in English, Mandarin and Cantonese).
The wonderful Cafe in the Crypt hosts two-hour jazz evenings (£8 to £15; £3.50 standing tickets, if concert sold out) at 8pm on Wednesday; there's also free lunchtime concerts at 1pm on Monday, Tuesday and Friday, and the shop offers brass rubbing for kids. Refurbishment excavations in the last decade unearthed a 1.5-tonne limestone Roman sarcophagus in the churchyard.
