 There is also one in Isfahan, Iran, called Monar Jonban (shaking minarets) with almost the same properties.A further example is a large mosque built by Makhdu-Ma-I-Jahan, mother of Sultan Qutubuddin Ahmad Shah II in 1454 A.D. She is buried in the mausoleum situated to the east of the mosque.Entry to the shaking minaret was prohibited following an incident in 1981 at Qutb Minar in Delhi, when a stampede resulted in the deaths of many children.
