Balban's Tomb
Located just near the entrance of the Archaeological Survey Park on the western side of Mehrauli-Gurgaon Road lies a 13th century tomb, popularly known as Balban's tomb. Balban was the last of the major Slave dynasty sultans who died in 1287 and was buried here.

The tomb is among the many ruined old structures of Mehrauli that are in a serious state of neglect. Ghiyathu'd-Din Balban's tomb is a rubble-built square chamber, open to the sky, with arched openings on all its sides. The chamber occupies an important place in the history of the development of Indo-Islamic architecture, as it is for the first time that true arches were used in a structure in India.

To the east of Balban's tomb is situated a ruined rectangular structure. It is said to contain the grave of Khan Shahid, Balban's son whose original name was Muhammad. He died fighting against the Mongols near Multan in 1285.
