For the longest time, the tomb of Mughal Empress Nur Jehan 1577-1645) has been a grazing ground for random cows and goats, which has destroyed much of its foliage, and a playground for street boys. Because the historical monument was not properly fenced from all its four sides, just about anybody could walk in — and do whatever they wanted to. You could even spot people hanging their clothes on the plantation, for drying.
The Empress must be turning in her grave, as her mausoleum — a glorious, red sandstone structure, built in her honour by Mughal Emperor Jehangir, her husband, in Shahdara Bagh — has been the victim of criminal neglect.
Historically, it is believed that the Tomb of Nur Jehan was renovated, during the reign of Maharaja Ranjit Singh. This actually stripped the monument of its original glory.
More recently, restoration work has started at the place. A boundary wall is being erected around the tomb. This should after all do the needful.
