Birla Planetarium

Built on the lines of the Buddhist Stupa at Sanchi, the MP Birla Planetarium isn't a museum, but is perfect for the traveller in Kolkata who has visited the Victoria Memorial and wants to rest his feet while letting the stars wash over him. India's oldest planetarium runs shows in Hindi, English and Bengali, and if you're there for longer in the city, you could sign up for an astronomy course. Rabindra Bharati Museum

The rambling Thakurbari built in the 18th century by Dwarkanath Tagore, grandfather of Nobel Laureate Rabindranath Tagore, has been converted into a museum now and hosts memorabilia that will delight the Tagore aficionado. It is part of the Rabindra Bharati University, which is also situated inside the Thakurbari complex. Calcutta Museum/ Kolkata Panorama
