It is the only remaining structure of what once was an entire city built by Feroz Shah Tughlaq in the 14th century. Its crumbling walls hold stories of djinns, or spirits that live for thousands of years at a time. A number of devotees offer candles, letters, rice and other items to appease them. Interestingly, the fort is built around the Ashokan Pillar built in the 3rd century. You'll also find Hawa Mahal, a baoli or round stepwell, and the ruins of three courts.
