Delhi's seven constituencies go to the polls on 12 May and those that vote will be permitted entry into the national capital's 90-acre heritage park Sunder Nursery, that surrounds the Mughal-era sandstone mausoleum Humayun's Tomb. "We are hopeful this will serve as incentive to many to actually vote," said AKTC CEO Ratish Nanda. Known as Azim Bagh in Mughal times, the park was conserved by cultural non-profit The Aga Khan Trust for Culture (AKTC) starting 2007.
