Cadogan Hall is a 950-seat capacity
concert hall in Sloane Terrace in
Chelsea /
Belgravia in the
Royal Borough of Kensington and Chelsea, London, England. The resident music ensemble at Cadogan Hall is the
Royal Philharmonic Orchestra (RPO), the first London orchestra to have a permanent home. Cadogan Estates offered the RPO the use of the hall as its principal venue in late 2001. The RPO gave its first concert as the resident ensemble of Cadogan Hall in November 2004. Since 2005, Cadogan Hall has also served as the venue for
The Proms' chamber music concerts during Monday lunchtimes and Proms Saturday matinees; it is also one of the two main London venues of the
Orpheus Sinfonia.
