Clare Hall Manor is a former health facility in Blanche Lane, South Mimms, Hertfordshire, England. It is a Grade II listed building.
The estate was formed in the early 18th century.[1] The house was built as a private residence in 1745 and became St Monica's Priory, a Roman Catholic nunnery, in 1886.[2] In 1896 the house was converted into a hospital so allowing the transfer of smallpox treatment services from Highgate Hospital; the new facility became known as Clare Hall Hospital.[2] Following substantial progress towards eradication of smallpox, the hospital converted to the treatment of tuberculosis patients in 1912 and became Clare Hall Sanatorium in 1929.[2]
In 1938, a series of brick huts, operated as part of the Emergency Medical Service, was built on the opposite side of Blanche Lane and were in use throughout the Second World War.[2] It joined the National Health Service as Clare Hall Hospital in 1948.[3]
After the hospital closed in 1974, the buildings were acquired by the London Research Institute which carried out biotechnological research at the manor.[2] After research services transferred to the Francis Crick Institute in 2015, Clare Hall was advertised for sale.[4]
