The Bethlem Royal Hospital in south London is the world’s oldest psychiatric institution, treating patients for nearly eight centuries.
Previously known as Bedlam, over the years the hospital has acquired a huge and significant collection of art and artefacts, much of it by patients. For years it has been stored in unsuitable temporary accommodation. On Thursday a new £4m gallery and museum to show off the collection opens to the public.
BBC News was given access to the new space to see how art can play a role in mental health and met one former patient whose work is included in the exhibition.
