Janbazar is broadly spread across Ward Nos. 46 and 52 of Kolkata Municipal Corporation. The road from Chowringhee to Circular Road, about a mile long, was called Jan Bazar Road till the end of the 19th century. It was then renamed Corporation Street and was further renamed
Surendranath Banerjee Road. In olden days, Kolkata streets had oil lamps. Then came the gas lamp and electricity. For sometime there was a tussle between gas lamps and electricity. In 1914, high-powered Keith lamps of 1,000 candle power were fixed on Corporation Street, and Chowringhee Road.
Calcutta Electric Supply Corporation bore the cost to demonstrate the advantage of electricity. Janbazar is served by New Market Police Station of
Kolkata Police.
