The Zeyn od-Din minaret is a historical minaret in Kashan, Iran. The founder of the minaret, Khaje Zeyn od-Din, was one of the dignitaries of the Timurid era in the 15th century. He also built a khanqah beside the minaret. It seems that minaret was originally 47 m high, but more than half of it was destroyed in 1931 by the decision of the governor and mayor of Kashan. Strong earthquakes during the centuries made the minaret lean.
