In a tangle of forgotten, overgrown brush in the heart of India’s capital, a quiet plan has been hatched to change the landscape of one of the world’s most populous cities. An intricate Mughal garden is being created. Crumbling sandstone tombs nearly lost to history are being rebuilt. An artificial lake is being carved out. The renovation of Sunder Nursery is intended to serve as the catalyst for an even more ambitious project: the creation of a mammoth, iconic park that would rival New York’s Central Park as a refuge from urban chaos.
