Patients are also referred to the hospital from many other parts of the world.The RNOH was founded in 1905 with the amalgamation of London's three specialist orthopaedic hospitals and can thus trace its history back to 1838.The hospital is located on two sites. The main site, the 'country branch', is located in 112 green belt acres at Stanmore with the 'town branch' located on Bolsover Street, central London. The town branch was also located at 234 Great Portland Street until 1984.During the First World War, the hospital became an emergency hospital for the military and in early 1918 also housed discharged disabled soldiers. King George V and Queen Mary visited the hospital on two occasions.
