Feroz Shah Kotla

New Delhi

Firozabad, the fifth city of Delhi, was built by Feroz Shah Tughlaq in 1354, the first city here to be built on the river. Only the fortress remains, with crumbling walls protecting the Jama Masjid (Friday mosque), a baoli (step-well), and the pyramid-like Hawa Mahal, topped by a 13m-high sandstone Ashoka Pillar inscribed with 3rd-century-BC Buddhist edicts. There’s an otherworldly atmosphere to the ruins.

Entrance is free after 2pm every Thursday when crowds gather at the mosque and other points of importance to light candles and incense and leave bowls of milk to appease Delhi’s djinns (invisible spirits), who are said to occupy the underground chambers beneath the ruins.

Shoes should be removed when entering the mosque and Hawa Mahal.
