The rubble masonry gateway, finished in plaster, is a simple structure when compared to the gateways it stands amidst the Humayun’s Tomb Complex . The eastern facade is chamfered at the corners and the centre portion treated with a large arched recesswhich encloses a slender arched opening in the centre of the facade, with jharokhas and an arched opening ofsimilar size repeated on the upper level.

Conservation works on this monumental gateway first required the removal of modern cement plaster from the façade and interior spaces. The plaster on the lower half of the façade was mostly lost and has been re-plastered on at least two occasions since 2001, and plasters using inappropriate modern mixes were used on both occasions thus accelerating the decay process for the lime plaster that remained. The new plaster was also found to be peeling off with deterioration caused due to a variety of reasons such as dampness, inappropriate mix, preparation and bonding between adjacent layers. After completely removing the added cement layers, the plastering works were commenced. Theplastering layers included coarse lime mortar for the base layer and fine lime mortar for the top layer, and then finished using a coat of 1 mm fine layer of lime punning comprisingof 1:1 ratio of lime and marble dust.

The parapet ornamented with the kangura motif, had also collapsed in portions and had benpoorly rebuilt. These have been reconstructed and tiles are restoredwhere they were missing. The internal chambers had ornamental plasterwork on the ceilings and medallions, though much ofitwaslost due to neglect over the years.These decorated surfaces had also beenrepaired in plain cement plaster during the earlier conservation efforts, which led to the loss of most ofthe decorated plasterworks.After careful documentation of the existing remains, the original patterns were discerned and therestoration works were carried out by the master craftsmen by replicating the existing patterns.These decorative patterns werethen finished with Lime punning and application of red polychromy.
