Clare Hall Manor

The estate was formed in the early 18th century.[2] The house was built as a private residence in 1745 and became St Monica's Priory, a Roman Catholic nunnery, in 1886.[3] 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.[3] Following substantial progresstowards eradication of smallpox, the hospital converted to the treatment of tuberculosis patients in 1912 and became Clare Hall Sanatorium in 1929.[3]

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.[3] It joined the National Health Service as Clare Hall Hospital in 1948.[4]

After the hospital closed in 1974, the buildings were acquired by the London Research Institute which carried out biotechnological research at the manor.[3] After research services transferred to the Francis Crick Institute in 2015, Clare Hall was advertised for sale.[5]
