Abject poverty mixes inexplicably with crumbling British Raj-era gems, sprawling gardens, and historical colleges. Long known as the cultural capital of India, Kolkata continues to spawn generations of poets, writers, film producers and Nobel Prize winners. If your trip only allows for a visit of one or two of India’s metropolitan cities, then definitely consider placing Kolkata on your itinerary. Love it or hate it, you definitely won’t forget the city on the Hooghly.
