Delhi is both a union territory within India, as well as a city, and features two very different worlds: New Delhi and Old Delhi. The former, inaugurated by the British in 1931 to serve as the imperial capital, is the nation's modern capital and seat of government, while Old Delhi is considered by many as the symbolic heart of the greater metropolitan area.

One of the most populous regions in the world, Delhi is a heady mix of tradition and modernity, important as both a religious center and India's busiest international gateway. Its history is as old as the ancient Yamuna River, one of the most sacred rivers in Hinduism and a natural dividing line between New Delhi to the west and Old Delhi to the east.

Things to see and do in Delhi and New Delhi are plentiful and include experiencing its diverse arts and crafts industry; its many magnificent monuments; countless performing arts venues; and its excellent cuisine, including delicacies from every corner of India. Delhi is also a shopper's paradise with numerous bazaars and markets, including Chandni Chowk, the country's most famous commercial area.
