Built during the lifetime of Hazrat Nizamuddin Auliya in the years 1321-22, this is the only Baoli in Delhi which still has underground springs. In July 2008, portions of the Baoli collapsed and after exhaustive scientific analysis and consultation with the community, conservation works to rebuild the collapsed portion could commence. For the first time in centuries, the Baoli was de-silted to its original depth of 80 feet below the ground level and major repairs including the removal of the 20th century epoxy layer carried out.
The vaulted southern arcade of the Baoli is contemporary to its Tughlaq construction as are possible the two domed pavilions on either side of its northern edge. The western side of the Baoli has three monuments – the Chini-Ka-Burj, Gogabai tomb and the Lal Chaubara while the eastern side has the vaulted corridor leading to the Dargah.
Following the completion of conservation of the Baoli, conservation effort a now focussed on the western facade where in addition to planned conservation works of Gogabai Tomb, Chini ka Burj, alterations to a residential structure are being carried out to restore the arcade seen in archival images.
Pir Khwaja Ahmed Nizami Syed Bukhari, Sajjadahnashin and Muttawalli, Dargah Hazrat Nizamuddin kindly agreed to push back his residential building standing atop the Baoli by 3 feet – the required space to reconstruct the arcade. The opportunity is also being taken to sensitively design the facade, so it does not disfigure the historic character.
Conservation works were carried out on this tomb which stands on Baoli end and could have served as entrances. This was in ownership of local community and in need of conservation. Works here ensured long term preservation, restoration of its original architectural character and its historical relationship with the Baoli.
It stands on the Baoli’s northern edge and was in private ownership and management. Due to its poor condition, the structure was used only for storage, and in a severe state of deterioration. After cleaning, decayed and weak areas were consolidated using lime based techniques and missing incised plaster work was reconstructed as per existing original pattern.
This 14th century tomb structure was in use as a store and had been altered to a greater extent with new construction all around. After removal of the paint layers, a detailed analysis was done required for the restoration of the decorative patterns. Missing incised plaster work of the medallions and original pattern of the ceiling have been restored.
Chini-Ka-Burj is a 16th century two storied structure, large portions of which had collapsed or been demolished making the structure inaccessible. Conservation work included construction of the partially collapsed dome, construction of missing masonry of the wall, structural repairs of the dome and the walls, lime plaster works, restoration of the glazed tile work and flooring.
