The Outstanding Universal Value of the Humayun’s Tomb World Heritage site is understood, amongst other factors, to be an ensemble of 16th century Tomb-Gardens. The Batashewala complex stands within the Buffer Zone of the World Heritage Site. Thus the reconstruction of missing portions of the enclosure wall that defined the significance of the complex was considered necessary.
During the scientific clearance of earthwork around the monument to determine original levels, the original foundations of the enclosure wall and a staircase on the southern side were discovered. It was also found that the Delhi Development Authority fencing was built almost on top of the western enclosure wall, this was demolished and the extensive vegetation and removal of debris was done to reveal the alignment of the 16th century wall.
The standing portions clearly revealed the plan of the wall including the depth and profile of the arcade. This was scientifically documented. A grand staircase in the centre of the southern side and aligned with the tomb chamber was revealed as well as a gateway in the western wall, again aligned with the tomb.
It was discovered that the enclosure wall of the Batashewala complex met the enclosure wall of the unknown tomb, thus establishing that the Mughal tomb predates the Batashewala complex. The profile of the arch in the elevated platform of the tomb was replicated for the enclosure wall as the profile of the two arches, in plan, were found to be similar.

The enclosure wall of the Mughal Tomb complex has been reconstructed completely as per the original details on the original foundations which have been strengthened by lime grouting thus restoring the setting of this 16th century structure. The enclosure wall was then provided with red sandstone of 7.5 cm thick plinth protection along the entire length. The remains of the staircase discovered here were documented carefully and it was reconstructed using the Delhi quartzite stone with lime mortar.
During the scientific clearance of earthwork in the immediate surroundings of the monument, a water tank and channel was discovered to the east of the tomb structure. The remains were documented prior to consolidation and were carefully incorporated in the garden restoration works.
Completion of all conservation works was followed by garden restoration where sandstone pathways were laid and Neem trees were planted.
