This is Shahjahanabad, the 17th century capital of the Mughal emperor Shahajahan of the Taj Mahal fame. Hail a cycle rickshaw and paddle into the madness – the streets are chockablock with auto rickshaws, horse tongas, bicycles, hand carts, pedestrians and of course, the clichéd cows. From a 'bone repair doctor' to barbers on the road, from crumbling havelis to a skyline of minarets and tombs, old Delhi lives up to its reputation. Soon-to-be brides come here to buy their wedding finery, in shops which are centuries old. Top off a meal at Parathewali Gali and then set out to explore the Moghul marvels of the Red Fort or the Jama Masjid. Don't miss the second hand book market that sets shop every Sunday.
