Built a century ago as a Christian Science church, this austere building was transformed into a light and airy auditorium in 2004, with an impressive expansion in 2014 to up the capacity. It's hard to imagine how the renovations could have been bettered: the classic hall is comfortable and the acoustics excellent, providing the perfect setting for concerts ranging from country to classical music (the Royal Philharmonic Orchestra are residents here).
Several of the BBC Proms concerts are held in Cadogan Hall every summer in conjunction with the Royal Albert Hall, and every November the London Jazz Festival sets up shop here. The early-twentieth-century interior is also a draw, as is the charming Oakley Room bar where drinks are served at every available juncture.
