Bidhannagar: The Planned Satellite City and IT Powerhouse of West Bengal
Commonly known as Salt Lake City, Bidhannagar is a meticulously planned satellite city located in the North 24 Parganas district of West Bengal. Serving as a vital part of the Greater Kolkata metropolitan area, it has transformed from reclaimed marshlands into one of Eastern India's most significant economic and technological engines.
Designed by Master Planner and Chief Architect Dobrivoje Tošković, the city's development began in the late 1960s. What started as a strategic reclamation project to alleviate population pressure on Kolkata has evolved into a modern urban center characterized by high-tech business districts, educational institutions, and significant recreational landmarks.

Historical Evolution and Etymology
The history of the region is deeply intertwined with the political shifts of mid-20th century India. During the Salt Satyagraha, the local community in Mahishbathan participated in the movement by producing salt using indigenous methods, led by the zamindar Lakshmikant Pramanik.
The modern city was born from a necessity to manage the mass influx of refugees following the partition. In 1948, Bidhan Chandra Roy, the second Chief Minister of West Bengal, conceived a reclamation project for the marshy salt lakes to the east of Kolkata. The landfill project was officially inaugurated on April 16, 1962. Following the completion of various sectors, the city was officially renamed Bidhannagar on April 5, 1973, to honor Roy's legacy.
Geography and Environment
Bidhannagar is situated within the lower Ganges Delta. The city's geography is unique due to its high water content; of its 55.51 square kilometers, roughly 25 square kilometers consist of water bodies. This includes the East Kolkata Wetlands, which is one of only two Ramsar sites in West Bengal, recognized internationally for its ecological importance.
