In 836, al-Mutasim, 8th Abbasid Caliph, bought land from Christian monastery and builds a military camp. al-Mutasim calls it surra man ra'a (pleased who see), later the area was abbreviated into Samarra.

The shrine was rebuilt over the centuries with the current look of the golden dome taking place in 1905. 72,000 gold pieces cover the dome which is approximated at 20 meters wide and 68 meters high. Both of its golden minarets are 36 meters high.
