Siri Fort, in the city of New Delhi, was built during the rule of Ala-ud-Din Khalji, the Turkic ruler of the Delhi Sultanate, to defend the city from the onslaught of the Mongols.
It was the second of the seven cities of medieval Delhi built around 1303 (stated to be the first entirely constructed by Turks), which at present is seen only in ruins with a few remnants (pictured)
Near the Siri Fort ruins modern auditoriums, the Asian Games Village Complex and residential and commercial establishments fill the modern landscape between the Khel Gaon Marg and the Aurobindo Marg in the heart of South Delhi.
