Shenley Hospital, Radlett Lane, Shenley was a Mental Hospital. The following comes from the 1937 Kelly's Directory:

The first section of the hospital, to accommodate 1,046 patients, was commenced in July, 1931, and was formally opened by H.M. King George V, who was accompanied by Queen Mary, on the 31st May, 1934. The second section of the hospital was constructed in 1937 on the villa system, to bring the whole accommodation in the hospital up to 2,080 beds. Shenleybury Farm had been re-conditioned and largely rebuilt to serve the needs of the Hospital, and the mansion was re-conditioned in 1937 for use as a Convalescent Home for the patients.
