Bidhannagar[a] (Bengali: বিধাননগর), also known as Salt Lake City is a planned satellite city of Kolkata in North 24 Parganas district in the Indian state of West Bengal. The population within city limits was 2,18,323 at the 2011 census, it has increased since 2001 census. After a successful extension of the city limits in June 2015, Bidhannagar's population increased to 6.7 lakhs residents. It is now the fourth-most populous city in West Bengal, after Kolkata, Howrah and Asansol.[1]

During the Salt Satyagraha, the people of Mahishbathan between present day Salt Lake and Rajarhat Newtown joined the Salt Satyagraha movement by preparing salt using indigenous methods. The main initiator of the movement was Lakshmikant Pramanik, the zamindar of Mahishbathan.[2]

Bidhannagar's Salt lake is a planned region of Kolkata. It was planned and developed between 1958 and 1965 to accommodate the burgeoning population of Kolkata.

Bidhannagar's Master Planner and Chief Architect was Dobrivoje Toskovic[3][4] from SFR Yugoslavia, now Serbia.

Bidhannagar (including Salt lake) in Kolkata metropolitan area is under the administration of Bidhannagar Municipal Corporation. Keeping with its original name, it is commonly referred to as Salt Lake City.[5]

Bidhannagar's architecture has modern landmarks, such as the Vivekananda Yuba Bharati Krirangan or Salt Lake Stadium.

The city is considered the main IT hub of Eastern India and Kolkata, West Bengal. Bidhannagar is located on the north-east side of Kolkata. The Nabadiganta Industrial area of Bidhannagar has always played a key role in the economic health of the city area. As of April 2019, Sector V of Bidhannagar had approx 1,500 company.[6] The East Kolkata Wetlands is recognized as a Ramsar site, located within the city limits of Bidhannagar.[7]


The city is named after Bidhan Chandra Roy, the founder of Salt Lake area of the city, and the second Premier of West Bengal (1948–1950) and first Chief Minister of West Bengal.
