In 1883 a temporary convalescent hospital for smallpox as set up by the Metropolitan Asylum Board (MAB). The site comprised tents and marquees for 300 beds, the largest civilian hospital camp at that time. In 1887 some temporary huts replaced a part of the camp and in 1890 a permanent hospital for convalescent smallpox patients was built on the higher ground above the camp. The two halves of the hospital were known as the "Upper" and "Lower" hospitals. The last of the tents were replaced by huts in 1902. In the following year the hospital changed its role slightly to cater for general convalescent fever cases rather than smallpox. It was transferred to the London County Council along with other MAB hospitals in 1930 following the Local Government Act, and in 1948 was transferred to the NHS. The hospital is now closed, date not known, and all buildings demolished and built over.
