In a chamber under the Feroz Shah Kotla Mosque.
The ruins of Firozabad, the fifth city of Delhi, stand tucked away next to a giant cricket stadium, just south of the former line of the walls of Old Delhi. It's not on most visitors itineraries, and even people I've know who have been living in Delhi for quite some time haven't gone there. The reason for this is, I think, relatively simple: Firozabad, otherwise known as Firoz Shah Kotla, is not pretty. Rather, it's scary, immensely atmospheric, and is generally considered one of Delhi's primary centers of supernatural activity....It's not for the faint of heart. Visiting the ruins on a Thursday afternoon, when people come from the surrounding area to petition disembodied spirits for favours and forgiveness in dark, dungeon-like chambers in the sad remnants of a once grand, but now almost totally destroyed, 700 year old city, is one of the most intense experiences that Delhi, a city that is nothing if not replete with intense experiences, has to offer.
