Of Delhi's two World Heritage sites, the Qutub Minar has been the poor cousin of Humayun's Tomb. For the Qutub, built in 1202 and given World Heritage status by UNESCO in 1993, has had neither an international organisation opting to landscape its gardens, nor hotel chains wanting to take up illumination work. The Qutub has had only the Archaeological Survey of India (ASI) for custodian and the local civic bodies looking after its precinct. UNESCO's guidelines for maintaining a buffer zone and core zone have never applied to Qutub, given ASI's helplessness over the surroundings.
