Mashobra is a town in Shimla district of Himachal Pradesh. It is connected to the state capital Shimla (earlier Simla) through the historic Hindustan–Tibet Road built in 1850 by Lord Dalhousie. Mashobra is located at 31.13°N 77.23°E. It has an average elevation of 2,146 meters (7,041 feet). Mashobra is notable for housing one of the two Presidential retreats in India. The other retreat is Rashtrapati Nilayam in Secunderabad. The president visits Mashobra at least once every year, and during this time his or her core office shifts to the retreat at Chharabra, in the vicinity of Mashobra. The building housing the retreat is a completely wooden structure originally constructed in 1850. In May 1948, before returning to London at the end of his mission as viceroy and then governor general of India, Lord Mountbatten and his wife Lady Edwina spent a few weeks in this retreat. The then Prime Minister Jawaharlal Nehru paid them a visit, which is documented in the biographies of Lady Mountbatten.
