On the western side of the Mehrauli bypass to Gurgaon there
are extensive ruins of old Mehrauli, now deserted. Among these, as the
visitor proceeds from the Qutub-Minar, he first encounters a domeless and
extremely dilapidated rubble-built square chamber with arched openings in
all its four sides, believed to be Ghiyath-ud-Din Balban's tomb.
It occupies an important place in the development of Indo-Islamic architecture, as one finds here for the first time the use of a true arch.
A ruined rectangular chamber on its east is believed to have contained the grave of Balban's son, Muhammad, who was popularly known as 'Khan Shahid' i.e., the Khan who became a martyr, after he died fighting in a battle against the Mongols near Multan in 1285. There exists also another tomb not very far away to the south, which is also popularly known as that of Khan Shahid.
