Tughlaqabad stands divided into three segments. The eastern segment is entered through from the Qutub-Badarpur road. It is a rectangular area enclosed within high walls and bastions and used to serve as the citadel. On the west side of the Tughlaqabad Fort is a wider area that once contained the palaces and is surrounded by walls and bastions. A huge reservoir stands on the southern side of the Tughlaqabad Fort at Delhi. Bunds were put up between hills to the east to create the reservoir, which is linked with Ghiyas-ud-Din's tomb through a causeway.
There is a wide mound near the south eastern-corner of the Fort Tughlakhabad of Delhi that leads to the fortress of Adilabad. The sluice gates near the mound were used for controlling water for irrigation purposes. There is also a tower, known as the Bijai-Mandal, inside the fort, along with remains of several halls, and also a long underground passageway. To the north of the fort, lies the city of Tughlaqabad, which is now mostly in ruins.
