As urbanisation spreads, how can heritage be saved? In the rushed transformation that Indian cities are undergoing can traditional homes, monuments, old engineering, rare water systems be conserved?

One such effort in New Delhi has produced outstanding results. Humayun’s Tomb has not just been restored, but now serves as an important historical landmark of the city. Tourists and schoolchildren in tens of thousands now visit the tomb, its splendid gardens and adjoining smaller monuments as well.
