Delhi is the capital of India, and it's also the travel hub of northern India. It's an excellent base for visiting Agra and the Taj Mahal, and the Rajasthani colour of Jaipur is less than five hours away. Travelers to Delhi get two cities for the price of one. 'Old' Delhi, the capital of Muslim India between the mid-17th and late 19th centuries, is full of formidable mosques, monuments and forts. It's a lively area of colorful bazaars, narrow streets and barely controlled chaos. In contrast, New Delhi, the imperial city created by the British Raj, is composed of spacious, tree-lined avenues and imposing government buildings, and has a sense of order absent in other parts of the city.
