Prominently located in axis with the principal entrance of Sunder Nursery stands the tomb now referred to as Sunder Burj. With exquisitely ornamented plasterwork on the ceilings, unique in Delhi, this early 16th century building is amongst the earliest buildings built during the Mughal reign and stands within the World Heritage Site Buffer Zone. In design, the building resembles Lakkarwala Burj and has a similar band of Quranic inscriptions encircling the inner walls at lintel level.
Beyond doubt, the most significant aspect of Sundarwala Burj is the ornamental ceiling of star patterns, comparable to a wall painting and reminiscent of the Persian wooden ceilings which were, most certainly, the inspiration for this early Mughal period building. The stucco work comprises of stars arranged in concentric circles with the cluster pentagons, generating from the crown of squinch arches arising from the four corners. The soffit of the squinch arches itself is decorated with stucco work forming a small dome supported by a network of arches.
