Sidi Bashir Mosque, Ahmedabad, Gujarat.

Sidi Bashir Mosque is a former mosque in the city of Ahmedabad, Gujarat, India. Only the central gateway and two minarets survive; they are known as the Jhulta Minar or Shaking Minarets.

The mosque is believed to have been constructed either by Sidi Bashir, a slave of Sultan Ahmed Shah, or by Malik Sarang, a noble in the court of Mahmud Begada, another Sultan of Gujarat. It has been dated to 1452, although the style and material of the minarets point to the close of Mahmud Begada's reign (1511) or later. The body of the building was destroyed in 1753 during the war between the Marathas and the Khan of Gujarat Sultanate; only two minarets and the arched central gateway connecting them remain.

 

Though much damaged, especially near the foot, the stairs inside the minarets may still be used. The minarets are three stories tall with carved balconies. A gentle shaking of either minaret results in the other minaret vibrating after a few seconds, though the connecting passage between them remains free of vibration. The mechanism of this is not known, although the layered construction is thought to be a factor. The phenomenon was first observed in the 19th century by Monier M. Williams, an English Sanskrit scholar.

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. There is also damage to the upper sections.
