The nucleus of Jaipur was the palace and garden of Jai Niwas, the foundations for which were laid in 1725. The building of the city and its surrounding walls and gates was started with due propitiatory rites ( sankalpa ) on 18 November 1727
The Vice Regal Lodge on the Observatory Hills, also known as Rashtrapati Niwas, was formerly the residence of the British Viceroy Lord Dufferin. It was the venue for many important decisions which changed the fate of the sub-continent. It is quite befittingly the only building in Shimla that occupies a hill by itself.
