Post-1939
At the start of the Second World War, Horsley Hall was still standing and requisitioned by the army. During the war, it was for training and accommodation by Number 12 Camp, Royal Pioneer Corp. Built in the formal gardens were Nissen huts, garages and military building. On 20 April 1950, Horsley Hall was mentioned in the House of Commons when a Member of Parliament raised a question about Lance-Corporal Sankey, Royal Warwickshire Regiment, never seen again and reported as a deserter after leaving the camp on 25 September 1944. In 1955, the army left the site. Horsley Hall, for a short time, was used as a private school but demolished in 1963. Until 1978 a feature of the gardens was a baroque gateway from Great Buckingham Street, London, where Peter the Great once stayed. Horsley Hall, and in the grounds, a dovecote and gazebo are Grade II listed buildings by CADW. The main reason for the listing is, "survival of a structure of an extensive Edwardian garden, with some massive rock work and a few fine ornamental trees". Some badly deteriorated parts of the hall remain, and the formal gardens are overgrown. The site is now privately owned with no public access.
