It was built by Altamash in 1231 for his son and heir-apparent Nasiruddin Mahmud, who died in battle in 1229 in Lakhnauti (Lucknow). It is built in the same style as the Quwwat-ul-Islam mosque and is assembled from assorted destroyed Hindu temples and other buildings.

You approach the octagonal tomb-chamber from a raised courtyard. Under a rubble-built platform the tomb is built like a crypt (ghar). The platform is encompassed by rows of columns on the east and west sides and the other sides are plain walls. These together with the domed parapets on the corners make the tomb look more like a fortress.

It is possible that the corridors of this tomb were at one time used as a madrasa. In the centre of the western wing there is a marble prayer niche which is richly and profusely embellished all over with verses from the Holy Quran.

Th exterior of the tomb had been grey sandstone to begin with, but Feroze Shah Tughlaq (1351-88) changed all that and had it faced all over with marble. Next to the Sultan Ghari tomb, lie the tombs of the other two sons of Altamash Ruknuddin Feroze Shah (died 1237) and Muizzudin Bahram Shah (died 1241), who occupied the throne of Delhi for very brief periods, before and after the sultan's favorite child and heir Raziya Sultana.
