The hospital was first known as the Broadmoor Criminal
Lunatic Asylum. Completed in 1863, it was built to a design by
Sir Joshua Jebb, an officer of the Corps of
Royal Engineers, and covered within its secure perimeter. The first male patients arrived on 27 February 1864. The original building plan of five blocks (four for men and one for women) was completed in 1868. An additional male block was built in 1902. Due to overcrowding at Broadmoor, an extending asylum branch was constructed at
Rampton Secure Hospital and opened in 1912. Rampton was closed as a branch asylum at the end of 1919 and reopened as an institution for "
mental defectives" rather than lunatics. During the
First World War Broadmoor's block 1 was also used as a
Prisoner-of-war camp, called Crowthorne War Hospital, for mentally ill German soldiers. After the escape in 1952 of
John Straffen, who murdered a local child, the hospital set up
an alarm system, which was activated to alert people in the vicinity, as well as the public including those in the surrounding towns of
Sandhurst,
Wokingham,
Bracknell,
Camberley and
Bagshot, when any potentially dangerous patient escapes. It was based on
Second World War air raid sirens, and a two-tone alarm sounded across the whole area in the event of an escape. Until 2018, it was tested every Monday morning at 10 am for two minutes, after which a single tone 'all-clear' was sounded for a further two minutes. All schools in the area were required to keep procedures designed to ensure that in the event of a Broadmoor escape no child was ever out of the direct supervision of a member of staff. Sirens were located at
Sandhurst School,
Wellington College,
Bracknell Forest Council depot and other sites until they were decommissioned upon the opening of the hospital's new site. Following the Peter Fallon QC inquiry into Ashworth Special Hospital, which reported in 1999, and which found serious concerns about security and abuses resulting from poor management, it was decided to review the security at all three of the special hospitals in England. Until this time each was responsible for maintaining its own security policies. This review was made the personal responsibility of Sir
Alan Langlands, who at the time was chief executive of the
NHS England. The report that came out of the review initiated a new partnership whereby the Department of Health sets out a policy of safety, and security directions, that all three special hospitals must adhere to. In 2015, the Care Quality Commission gave the hospital an Inadequate rating. In 2018, the hospital was rated as Good overall by the Care Quality Commission. ==Therapies==
