Great Mosque of Samarra: The Spiral Minaret of the Abbasids

The Great Mosque of Samarra is a ninth-century congregational mosque in Iraq, built between about 848 and 852 by the Abbasid caliph al-Mutawakkil. For several centuries it was the largest mosque in the world, and its spiral minaret, the Malwiya, remains one of the most recognisable buildings of the early Islamic world. Its ruins are the best-known monument of Samarra, the city that served as the capital of the Abbasid Caliphate for more than half a century.

Samarra: a new capital on the Tigris

In 836 the caliph al-Mu’tasim left Baghdad and founded a new capital about 125 kilometres upstream on the Tigris. The move was largely driven by his army of Turkish slave soldiers, whose presence had caused friction with the population of Baghdad. Samarra, whose full name was later glossed as Surra man ra’a (“a joy for whoever sees it”), grew rapidly into a sprawling city of palaces, barracks and avenues.

The city stretched for more than 40 kilometres along the river, one of the largest urban areas of the medieval world. Successive caliphs added palaces and racecourses. The court remained there until 892, when the caliph al-Mu’tadid returned to Baghdad. Because Samarra was largely abandoned afterwards, much of its plan survived, making it one of the best-preserved early Islamic cities.

Building the mosque

Al-Mutawakkil, caliph from 847 to 861, was one of Samarra’s greatest builders. Around 848 he began a new Friday mosque in the city’s centre, replacing an older and smaller mosque of al-Mu’tasim. Work was completed in about 851 or 852. A second, smaller mosque with a similar spiral minaret, the Mosque of Abu Dulaf, was built in his new northern suburb of al-Mutawakkiliyya around 859–861.

The Great Mosque was built of fired brick. Its outer wall enclosed a rectangle of about 240 by 156 metres, strengthened by 44 semicircular towers. Around this lay a further enclosure, the ziyada, which separated the sanctuary from the bustle of the city. Including these outer zones, the complex covered more than 15 hectares.

Inside, a vast open courtyard was surrounded by roofed halls. The prayer hall on the south side, facing Mecca, had a flat timber roof supported by a forest of brick piers. Excavations found fragments of glass mosaic and marble that once decorated the prayer niche (mihrab). Early sources say the mosque could hold many thousands of worshippers at Friday prayers.

The Malwiya minaret

The mosque’s most famous feature stands outside its north wall: the Malwiya, from an Arabic word meaning “twisted” or “spiralled”. It rises from a square base to a height of roughly 52 metres, with an external ramp that circles the cone-shaped tower five times, turning anticlockwise as it rises, to a small platform at the top.

Spiral minarets are rare in Islamic architecture. Scholars have long debated where the idea came from. Some have compared it with the stepped temple towers (ziggurats) of ancient Mesopotamia, whose ruins were still visible in Iraq; others see it as a new design intended to make the caliph’s mosque visible across the flat landscape. There is no firm evidence settling the question.

The minaret was probably less a practical place for the call to prayer than a monumental statement of Abbasid power. A later anecdote claims al-Mutawakkil rode up the ramp on a donkey, but this cannot be verified.

Key people

• Al-Mu’tasim (r. 833–842): founded Samarra in 836 and built its first congregational mosque.
• Al-Mutawakkil (r. 847–861): commissioned the Great Mosque and the Abu Dulaf Mosque. He was murdered in 861 by members of his Turkish guard in a plot involving his son al-Muntasir.
• Ernst Herzfeld (1879–1948): German archaeologist who led excavations at Samarra in 1911–1913, recording the mosque and its stucco decoration.

Influence and later history

The Samarra style spread across the Islamic world. Its carved and moulded stucco patterns were copied widely, and the Mosque of Ibn Tulun in Cairo, built in 876–879 by a governor who had grown up in Samarra, borrowed its brick piers, its ziyada and, in its minaret, the idea of an external spiral stair.

After the court left in 892 Samarra declined, and the Great Mosque fell into ruin. The roof and prayer hall disappeared, but the massive outer walls and the minaret survived. Modern study began with Herzfeld and continued with the architectural historian K. A. C. Creswell and, later, the survey of Samarra’s topography by Alastair Northedge.

In April 2005, during the Iraq War, an explosion damaged the top of the Malwiya after US troops had used it as an observation post. In 2007 UNESCO inscribed the Samarra Archaeological City as a World Heritage site and, because of the security situation, immediately placed it on the List of World Heritage in Danger.

Why it matters

The Great Mosque of Samarra shows the ambition and wealth of the Abbasid caliphate at its height. Its scale was unmatched for centuries, its decoration set fashions from Egypt to Central Asia, and its spiral minaret has become a symbol of Iraq’s heritage.
