The idea to restore Humayuns' tomb started in 1997 by the Archaeological Survey of India (ASI) in collaboration with the Aga Khan Trust for Culture (AKTC) - the first private partnership to conserve a national monument. An MoU was signed with the ASI in 1999 as it was the first time any private player came forward to offer funds and restore any national monument in India, recalls Ratish Nanda, CEO of AKTC, who has been relentlessly working on the projects. There were major challenges not just in restoration and conservation, but also in urban planning where the Aga Khan Development Network (AKDN) decided to intervene and uplift the lives of the urban millennials residing in these areas. Today this has become a classic case study for private players and government to emulate in heritage conservation.
