The image is a photograph of a sign in India that reads "The Humayun's Tomb-Nizamuddin area is one of the densest ensemble of medieval Islamic buildings in India, inhabited by a vibrant local community being visited by millions of tourists and pilgrims each year. Conservation works being undertaken on the monuments in this area are in adherence with the established Indian and international conservation philosophy and principles. It strongly maintains authenticity of the original design in both form and material by employing hundreds of master craftsmen working with traditional building materials. All conservation work is preceded by archival research, high definition surveys, structural assessments and peer review. The Aga Khan Historic Cities Programme projects promote the conservation and use of buildings and public spaces in historic cities in ways that can spur social, economic and cultural development."
