Manar-e Jonban (the Shaking Minarets) is an architectural wonder on the outskirts of Esfahan that was built in the 14th century over the grave of a local hermit and holy man named Amu Abdullah Soqla. The minarets are often shaken for tourists because when one is shaken from the inside, the second one also sways. It's not entirely clear whether the minarets were specifically designed to behave this way or whether the phenomenon developed over time.
