The Menar Jonban (shaking Minarets) is a mosque in Isfahan in Iran. It was built in 14th century to cover the grave of Amu-Abdollah Soqla. It special features is that if either of Minarets is shaken, the other minaret will vibrate as well. The Ivan and the porch were probably erected shortly after 1316 to cover the grave of Amu-Abdollah Soqla, a hermit, who was buried here. There are also pieces of marble stone on the grave that Holy Quran "Yassin" was written on that and makes it more beautiful. There are other inscriptions in the tomb, including inscriptions on the marble top of the original stone Anobanini, the righteous and pious uncle as a man named Abdollah.
The mausoleum was built while the minarets were added later by architect Sheikh Bahai. The architectural style of the monument is that of the Mongol period and completed with dark blue tiles in the form of stars decorating two arches and the sides of the portico.
The minarets are of later, probably Safavid origin and are largely responsible for the fame of the otherwise unremarkable shrine. Because of the ratio between the height and width of the minarets and the width of Ivan if you climb into one minaret and shake it, the other will shake in unison.
The wooden beams on the upper part of the minarets have been placed there to facilitate the shaking of the minarets, but the presence of wood in the brickwork causes other complication. Shaking is in theory restricted to once every twenty minutes, however, particularly during holidays, there is a constant stream of visitors who experiment with phenomena and visitors will have ample chance to observe it from ground level without running the risk of being blamed for any further dereliction.
In the past time, they didn't shake the Minarets and people just went up the stairs and felt no shaking but now a days, with in a specific time, it's been nearly about two years they are shaking (the minarets) and it's a special feature in this building and you can go up the stairs and enjoy your time.
The porch is 10 meters high and 10 meters in width the minarets are 7 meters taller and are 4 meters in circumference. There are two rooms in this building that is known as Chele Khune.
