The Mausoleum of Awn ibn Ali (Persian: بقعه عون بن علی) or Imamzadeh Awn ibn Ali/Imamzadeh Zayd ibn Ali[2] is a mosque and shrine located on the Eynali mountain which is north of Tabriz, Iran.[3] The shrine dates back to the 14th century and it contains two tombs, said to be of two sons of Ali ibn Abi Talib.[2][3][1] It is also one of the many Imamzadeh shrines of Iran.
The site of the building was originally a Zoroastrian fire temple which was converted into a mosque during the Rashidun conquest of Persia.[1] During the Ilkhanate era, the building was rebuilt into a shrine-mausoleum for Awn and Zayd, two sons of Ali ibn Abi Talib.[3][2]
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.[2] Later on, the 1641 Tabriz earthquake completely destroyed the mosque and shrine.[2] Many years after Safavid rule had ended, the building was restored during the Qajar period, by Jalal al-Din Mirza Qajar.[2]
