Probably the oldest continuously inhabited region in Delhi, the area around the Qutb Complex, commonly known as Mehrauli, is the site of Delhi’s oldest fortified city, Lal Kot, founded by the Tomar Rajputs in AD 1060.
The Turks invaded the city of Lal Kot in AD 1192 and with this brought in the Sultanate rule. The Quwwatul- Islam Mosque (1192) is a masterpiece of Indo-Muslim art and one of the oldest mosques in India.
Probably the most significant building of early Sultanate rule is the Qutb Minar (A UNESCO World Heritage Site) built in the early part of the thirteenth century. Around the Qutb are important buildings like Iltutmish’s Tomb(1235), the magnificent Alai Darwaza (1310), and Alauddin’s Madrasa (1317) built by later sultans such as Iltutmish and Alauddin Khalji.
Alauddin Khalji also started to build another minar, that was meant to overshadow the Qutb Minar completely. The construction of this building was abandoned after his death and today, only a rubble base known as the Alai Minar remains.
