Initially, the main tomb was enclosed within rectangular walls, built of rubble. This chamber was constructed by Muhammad Bin Tughlaq, who later added a small gateway on both sides of the tomb. However, the original Chiragh-I-Dili Dargah has undergone renovations and repairs a number of times. Now, a twelve-pillared square chamber, enclosed within perforated screens, consists of the tomb of Nasir-ud-Din Mahmud. The chamber has four small domed towers at the corners and is surmounted by a plastered dome, rising from an octagonal drum.
A number of structures, like the Majlis-Khana (assembly hall), Mahfil-Khana (symposium hall), were added to the Delhi Chiragh-I-Delhi Dargah some time back. The structure also comprises of a graveyard, which houses the graves and tombs of several distinguished personalities. Last but not the least, there are a number of mosques situated inside the premises of the dargah. One of these mosques was built by King Farrukhsiyar, in the early 18th century, in the honor of Nasir-ud-Din Mahmud.
