Bidhannagar or Salt Lake City as it is popularly called, is a planned satellite town in the Indian state of West Bengal. It was developed between 1958 and 1965 to accommodate the burgeoning population of Kolkata, the state capital. It is now a hub of economic and social expansion and is famous as the center for IT in the city. Dr. Bidhan Chandra Roy, the then Chief Minister of West Bengal, was instrumental in formulating the plan to build this satellite area, and the township was named Bidhannagar in his honor. The city was built on a reclaimed salt-water lake, which gave rise to its popular name of "Salt Lake City"
