Mausoleum of Awn ibn Ali

The Mausoleum of Awn ibn Ali or Imamzadeh Awn ibn Ali/Imamzadeh Zayd ibn Ali is a mosque and shrine located on the Eynali mountain which is north of Tabriz, Iran. The shrine dates back to the 14th century and it contains two tombs, said to be of two sons of Ali ibn Abi Talib. It is also one of the many Imamzadeh shrines of Iran.

History
The site of the building was originally a Zoroastrian fire temple which was converted into a mosque during the Rashidun conquest of Persia. During the Ilkhanate era, the building was rebuilt into a shrine-mausoleum for Awn and Zayd, two sons of Ali ibn Abi Talib.

The mosque and shrine were damaged in the events following the Battle of Chaldiran. The building was then rebuilt during the reign of Shah Abbas I. Later on, the 1641 Tabriz earthquake completely destroyed the mosque and shrine. Many years after Safavid rule had ended, the building was restored during the Qajar period, by Jalal al-Din Mirza Qajar.
