Aga Khan revives lost 16th century Mughal garden in heart of Delhi 300,000 children visit Humayun's Tomb every year and we could triple that. The first stage of the new park has already been transformed. Until recently it was an overgrown parched jungle of scrub, a dump site for building rubble, home to packs of street dogs and migrant workers, with the air of an abandoned public lavatory. Its Mughal era tombs - sited as close as possible to the auspicious shrine of the Sufi saint Nizamuddin - had been raided for architectural salvage and were overgrown and vandalised. Its trees - a rare collection of the most exotic from throughout the British Empire - had been reclaimed by wild creepers. A small army of gardeners, labourers, landscape and conservation architects are now on course to open the first 170 acre section in 2015. They have removed more than 1,000 trucks of dumped rubble, cleared acres of wild jungle, levelled the ground and laid modern versions of classical Persian gardens with hand-carved marble and sandstone fountains and water channels. The Lakkarwala Burj tomb has been restored and set in a new rose garden, while craftsmen have recreated entire sections of white Quranic verses on the red sandstone interior walls of the Sunderwala Burj tomb. The Sunder Nursery project will eventually employ hundreds of craftsmen, security guards, gardeners, managers, musicians and teachers from the Nizamuddin Basti, one of India's poorest communities, and will become self-financing through entry charges. Very few, if any, of the world's great parks have their own unique musical culture, and the Sunder Nursery will showcase it with regular Sufi Qawwali concerts - the devotional singing and clapping which can transform followers into Whirling Dervishes. "We have built an amphitheatre for events because this area has a 700 year old musical legacy, the Qawwali tradition was born here," Mr Nanda said.
