Great Mosque of Samarra / Jami al-Mutawakkil
Patron: Caliph al-Mutawakki
Abbasid period, 847-61 AD
In 836 AD, the Abbasid Caliph al-Mu’t, wishing to escape conflict with the local population in Baghdad, moved to Samarra, which remained the seat of power for the Abbasids for next 56 years, a period during which the largest mosque in all of Islam was built at Samarra.
The Great Mosque of Samarra was at one time the largest mosque in the world; its minaret, the Malwiya Tower, is a vast spiralling cone 52 meters high and 33 meters wide with a spiral ramp. The mosque had 17 aisles, and its walls were panelled with mosaics of dark blue glass.
