The Teen Murti Bhavan is a building and former residence in New Delhi. It was built by the British Raj and became the residence of the first Prime Minister of India, Jawaharlal Nehru, who stayed there for 16 years until his death on 27 May 1964. It was designed by Robert Tor Russell, the British architect of Connaught Place and of the Eastern and Western Courts on Janpath during the British Raj. Teen Murti Bhavan was built in 1930 as part of the new imperial capital of India, New Delhi, as the residence of the Commander-in-Chief of the British Indian Army. This imposing structure covers a massive area of 30 acres and was carved out of white stone and stucco to give it its signature look.
