India is fortunate in its building craft traditions, which have been passed down through many generations and over a number of centuries. Craftsmen here still take great pride in replicating the work of their forefathers, using tools and building techniques seen depicted in Mughal miniatures. Craftsmen clocked over 100,000 man-days of work to complete the conservation work here. The use of traditional materials, especially lime plaster – even when prepared in a traditional manner – will appear “new” at the onset, but over time the patina comprising organic growth will return on account of the jaggery, lentils, egg whites, pulp of the bael fruit that has been used as additives in the lime mortar. At the same time, the traditional methods will ensure the long-term preservation of these sites. The Outstanding Universal Value of the Humayun’s Tomb World Heritage site is understood, amongst other factors, to be an ensemble of 16th century tomb-gardens. Thus the reconstruction of missing portions of the enclosure wall that defined the significance of the complex has enhanced the historic character.
