The Tomb of Ghiyas ud din Balban was built in year 1287 CE in rubble masonry It is a building of historical importance in the development of Indo-Islamic architecture, as it was here that first Islamic arch made its appearance in India and according to many, the first Islamic dome as well, which however hasn't survived.

This structure is the Tomb of the ninth ruler of the Mamluk Dynasty of the Delhi Sultanates and widely considered one of the greatest for having defeated a Mongol invasion and for defeating rebellions when local rulers of parts of the empire attempted to assert their independence. Sadly the tomb is mostly in ruins with only high walls and arches evidence of what must’ve been a very large building, although it doesn't seems to have the ornate decorations of Indo-Islamic type royal tombs. The cenotaph can be found in the ruins and probably marks the grave of Balban. Not a must-see in the park, especially as it requires going over rough ground.
