Mehrauli in South Delhi is home to the 200-acre Mehrauli Archaeological Park, which is right next to Qutub Minar, a World Heritage Site. It is one of the lesser known sites yet full of rich historical culture. This heritage park is also one of the few sites in Delhi that continues to be inhabited in contemporary times. There are more than 100 notable historical monuments there including the ruins of Lal Kot, the oldest existing fort in Delhi which was built by Tomar Rajputs in the 11th century. It also contains architectural remnants from later periods, including those of the Khalji dynasty, the Tughlaq dynasty, the Lodhi dynasty of the Delhi Sultanate, the Mughal Empire, and the British Raj.
