At Delhi's Kotla Firoz Shah, believers petition the djinns every Thursday

Kotla Firoz Shah, the 14th-century fort complex on Delhi's Bahadur Shah Zafar Road, was built by Sultan Firoz Shah of the Tughlaq dynasty as part of Firozabad, Delhi's fifth city. Today the ASI monument is known for its unseen residents: every Thursday, hundreds of believers visit to appeal to the djinns, supernatural beings rooted in Islamic belief and folklore.
