Kolkata (formerly Calcutta) is the capital of India's West Bengal state. Founded as an East India Company trading post, it was India's capital under the British Raj from 1773–1911. Today it’s known for its grand colonial architecture, art galleries and cultural festivals. It’s also home to Mother House, headquarters of the Missionaries of Charity, founded by Mother Teresa, whose tomb is on site. Next is Sundarban. The Sundarbans is a vast forest in the coastal region of the Bay of Bengal; considered one of the natural wonders of the world, it was recognised in 1997 as a UNESCO World Heritage Site of Bangladesh.
