Tughluqabad Fort is a ruined fort in Delhi, built by Ghiyasuddin Tughluq, the founder of the Tughlaq dynasty, of the Delhi Sultanate of India in 1321, as he established the third historic city of Delhi, which was later abandoned in 1327. It lends its name to the nearby Tughluqabad residential-commercial area as well as the Tughluqabad Institutional Area. Ghiyasuddin Tughluq also built the Qutub-Badarpur Road, which connected the new city to the Grand Trunk Road. The road is now known as Mehrauli-Badarpur Road. The entry fee for the Fort is Rs. 20 for Indians. Also, nearby is Dr. Karni Singh Shooting Range and Okhla Industrial Area. Surroundings are an important biodiversity area within the Northern Aravalli leopard wildlife corridor stretching from Sariska Tiger Reserve to Delhi. Historical places around the sanctuary are Badkhal Lake, 6 km (3.7 mi) northeast, the tenth century ancient Surajkund reservoir and Anangpur Dam, Damdama Lake, Tughlaqabad Fort and Adilabad ruins (both in Delhi). It is contiguous to the seasonal waterfalls in Pali-Dhuaj-Kot villages of Faridabad, the sacred Mangar Bani and the Asola Bhatti Wildlife Sanctuary. There are several dozen lakes formed in the abandoned open pit mines in the forested hilly area of Delhi Ridge. From Wikipedia
