India's Golden Triangle comprises the three most visited cities in the country's north-west - Delhi, Agra and Jaipur,been dubbed "golden" for the extraordinary wealth of cultural and historical splendour on offer in each of the three cities.Jaipur, capital of the largely desert state of Rajasthan, is home to some of Asia's best bazaars. You could spend weeks in Delhi, the sprawling, fascinating Indian capital, and not see it all, while Agra, once the heart of the Moghul empire, boasts the unparalleled beauty of the Taj Mahal, which adorns the banks of the Yamuna river. Delhi's chief "sight" is its street life. The teeming bazaars of imagination lie in "Old" Delhi, the city of the Moghuls, established in the 17th century and still largely Muslim: the immense Jama Masjid (Great Mosque) dominates the quarter. Its main thoroughfare, the tumultuous Chandni Chowk, abuts the Red Fort, whose pristine lawns and lofty Moghul audience halls offer a tranquil haven.
