Mashhad, Iran
Imam Reza Shrine
Ali al-Rida (Imam Reza)
The mausoleum of Ali al-Ridha, the eighth Shia Imam, in Mashhad, Iran. It is the most-visited pilgrimage site in Islam, drawing an estimated 30 million pilgrims a year, and at 1.2 million square meters is the third-largest mosque complex in the world after the two holy mosques of Mecca and Medina. Imam Reza was poisoned in 818 CE on the order of the Abbasid caliph al-Ma'mun and buried beside the earlier grave of caliph Harun al-Rashid; the site became known as Mashhad al-Ridha, "the place of martyrdom of al-Ridha." A modest domed structure first appeared over the grave by the end of the 9th century, and the shrine has been destroyed, plundered, and rebuilt many times since — by Ghaznavid and Seljuq rulers, then reconstructed on a grand scale under the Mongol convert Öljaitü, the Timurids (whose Empress Goharshad funded the adjoining mosque bearing her name in 1418), and the Safavids, who made Mashhad a center of Twelver Shi'ism after 1501. The complex now spans seven courtyards and 14 minarets, and also houses a museum, library, several seminaries, and a university. It has twice been the site of violent state repression — the 1935 Goharshad Mosque massacre under Reza Shah, and a shooting in 1978 under his son — as well as a 1994 bombing and a 2022 stabbing attack that killed two clerics.
