On the Observatory Hills is located Viceregal Lodge, which is also known as Rashtrapati Niwas. This magnificent building was the residence of the British Viceroy Lord Dufferin. This lodge was completed in 1888 and it is said that every brick for the building was carried by mules. This is a six-story building and is surrounded by well-maintained gardens and lawns. The lodge has now been converted into Institute of Advanced Study and is further 2 Km from State Museum.
