Landour was initially built by and for the British Indian Army. From 1827 when a sanatorium was built in Landour, the town was a convalescent station for the military, and hence much of Landour is a Cantonment. The original sanatorium is now occupied by the Institute of Technology Management ("ITM") of the DRDO; it is at the eastern end of the Landour ridge. In the early 20th century, a full British Military Hospital (BMH) was opened, with a medical staff that specialized in tropical diseases; the hospital closed soon after 1947. Also within the ITM premises is the former Soldiers' Furlough Home, a holiday home for British and Irish soldiers and JCOs in Indian regiments who lacked the means to return to Europe regularly. Or, the holidaying soldiers were serving in British regiments on rotation in India, their tours of duty lasting anywhere from 6 to 48 months. In terms of area, Landour Cantonment comprises about two-thirds of Landour; the remainder includes Landour Bazaar, which stretches along the spur that connects to Mussoorie.
