The Humayun Tomb World Heritage Site Museum has been in the making for nearly a decade, but restoration and urban renewal initiatives in the 300-acre Nizamuddin Conservation Area, of which Humayun's Tomb is a part, have been ongoing for 25 years. The museum is the crowning glory of that grand project, which has given us the resplendent Humayun's Tomb, Sunder Nursery and its historical monuments, a restored Sabz Burj which historian Ebba Koch has surmised as the tomb of Humayun's mother, and community affirming projects in Hazrat Nizamuddin Basti. The creation of the site museum, set in the entrance zone of the Humayun's Tomb Complex and the Sunder Nursery Heritage Park, was spearheaded by the Aga Khan Trust for Culture (AKTC) in partnership with the Archaeological Survey of India (ASI), all under the watchful eye of conservation architect Ratish Nanda, who heads AKTC in India.
