Birla Industrial & Technological Museum

The original science museum in the city, Birla Industrial & Technological Museum on Gurusaday Road has been around for over half a century. It doesn't have the technological glitz of Science City, but it is still a great way to relive the early days of technology. Do check out the industrial models showcased here.

Nehru Children's Museum

It's been around in Kolkata for over 30 years, but blink and you'll miss the unassuming building housing the Nehru Children's Museum. Situated amid the bustle of Chowringhee Road, the museum is a great favorite with children. Most of the exhibits here are quaint, but the elaborate display on the great Indian epics - the Ramayana and the Mahabharata - is worth a visit.
