Following a decade-long revitalisation effort undertaken by the Aga Khan Trust for Culture, which included the conservation of monuments, restoration of parks and gardens and related socio-economic projects in neighbouring districts, the Humayun's Tomb Complex now receives almost two million visitors annually. Over 500,000 of them are school children. A greater number of pilgrims - from across the world and of many faiths - visit the adjoining Dargah of Hazrat Nizamuddin Auliya, the 14th century Sufi saint who continues to be revered seven centuries after his death.

A state-of-the-art site museum is to be built at the entrance of the World Heritage Site to: enhance visitor experience; allow a better understanding of Mughal architecture and building craft traditions; shed light on the development of the Nizamuddin area over a millennium; and, most significantly, explain the pluralist Sufi cultural traditions that defined Hindustani culture for at least five centuries. This will be the first of the Site Museums planned for the 25 Adarsh or "model" monuments recently designated by the Government of India's Ministry of Culture.
