NEW DELHI: A once-forgotten Mughal garden in the heart of New Delhi reopened on Wednesday after years of painstaking conservation work, creating a new public park in India’s sprawling and smog-choked capital. The 90-acre (36-hectare) garden will be formally opened by the Aga Khan, whose Trust for Culture has helped recreate the classical garden and restore its crumbling 16th-century monuments. Some of the ancient tombs it contains were close to ruin before conservation efforts began around a decade ago, but have now been given UNESCO World Heritage status. The park is part of the historic complex that surrounds Humayan’s Tomb, the recently restored grave of a Mughal emperor that is widely seen as the inspiration for the Taj Mahal.
