In the 17th century, Mughal Emperor Shah Jahan built his new walled capital, Shahjahanabad, which is now known as Old Delhi (relative to the British New Delhi that came immediately after). Today’s Old Delhi is one of the most fascinating parts of Delhi. It is a maze of lanes, by lanes, cramped residences, decaying mansions, bazaars of all kinds, shrines of all faiths, lots and lots of people, and an amazing array of north Indian street food, steeped in stories and culture.
