15 Fascinating Facts About Imam Reza Shrine Complex

The Imam Reza Shrine in Mashhad is one of the largest religious complexes in the world by area, spanning approximately 598,657 square metres — larger than Vatican City. It is centred on the tomb of Imam Reza (765–818 CE), the eighth imam in Twelver Shia Islam, who was buried in Mashhad (meaning 'place of martyrdom'). The complex grew from a single shrine over a thousand years into a vast city-within-a-city, encompassing seven courtyards, multiple prayer halls, the Goharshad Mosque (1418 CE), museums, libraries, a university, and a hospital. The golden dome and gilt minarets are visible from across the city. Non-Muslim visitors may enter the outer courtyards but not the shrine's inner sanctum. It draws an estimated 25–30 million Shia pilgrims every year, making it the most visited pilgrimage site in the Islamic world after Mecca and Medina.
