The teetotaller's hospital: Removing drink from Victorian medicine
For hundreds of years alcohol was widely used in medicine, both as a therapy in its own right and as well as a carrier for other substances.
In 1873, a group committed to removing alcohol from medicinal practice set up the London National Temperance Hospital, which later became simply the National Temperance Hospital.
It closed in 1990 and now stands derelict.
BBC News visited the hospital for a look at its work, its legacy and the future of the building.
