Viceregal Lodge, now known as Rashtrapati Niwas, stands on Observatory Hill in Shimla and was built as the summer residence of the Viceroy of India. Designed by architect Henry Irwin, construction began in 1886 and the building was completed in 1888 during the tenure of Lord Dufferin, who occupied it from July 1888. The project reportedly cost approximately ₹38 lakh, reflecting the importance attached to creating a grand imperial residence in the Himalayan capital. Today, the building houses the Indian Institute of Advanced Study.
The Lodge played an important role in the political history of British India. Several significant discussions and meetings took place here, including the Simla Conference of 1945. Following independence, the building served as a retreat for the President of India before being transferred to the Indian Institute of Advanced Study in 1965.
