During the Partition of India, in August 1947 the Purana Qila together with Humayun's Tomb, became major refugee camps for Muslims migrating to the newly founded Pakistan, and was later managed by the government of India.

The camps were raided many times by jathas which caused vandalism to occur during the early partition days in 1947.

An important phase in the restoration of the complex began around 1993, when the monument was declared a World Heritage Site. This brought new interest to its restoration, and a detailed research and excavation process began under the aegis of the Aga Khan Trust and the ASI. This culminated in 2003, when much of the complex and gardens were restored, with the historic fountains running once again after several centuries of disuse.

While the prevailing style of architecture was trabeate, employing pillars, beams and lintels, this brought in the arcuate style of construction, with its arches and beams, which flourished under Mughal patronage and by incorporating elements of Indian architecture, especially Rajasthani architecture including decorative corbel brackets, balconies, pendentive decorations and indeed kiosks or chhatris, to develop a distinct Mughal architecture style, which was to become a
