Built by pub owner John Wilton in 1858, Wilton's is the world's oldest surviving extant music hall, built on the back of a pub. It was closed in the 1880s and later became a Methodist church and then a rag warehouse. Once condemned, the Grade II-listed building was saved by the intervention of Sir Laurence Olivier, Peter Sellers and Sir John Betjeman and was, in 2003, a finalist in the BBC series of Restoration (See News, 11 Sep 2003). Though only 40 percent of the Music Hall is safe and in use, it now plays host to a select number of theatrical and musical events each year. The Wilton’s Music Hall Trust has been set up to stabilise the building, at an estimated cost of £4 million.
