The largest metropolis in India, Calcutta is a vibrant city on the move, volatile and unpredictable.

The Gateway to India, till 1912, and the capital of the Raj in India, it still bears the Victorian imprint on its streets and structures.

A city just about ready to burst at the seams, Calcutta is home to more than 10 million people.

It is the commercial nerve-centre of the East, with major industrial plants, textile mills and corporate units.
