History

The Great Mosque of Samarra is a ninth-century Abbasid congregational mosque in Samarra, Iraq, commissioned by Caliph Al-Mutawakkil and built between 848 and about 851. The Abbasids were the ruling dynasty of the Islamic caliphate from the eighth to the thirteenth century. During its construction, the mosque was the largest in the world and formed part of Samarra’s eastward expansion into an old hunting park.

An Abbasid capital project

The mosque stood beyond Samarra’s principal urban area, beside a palace complex and near residential districts. As the city’s congregational mosque, it served local inhabitants as well as visitors and foreigners. It contained a minbar, the pulpit used for the Friday sermon, and a mihrab, the prayer niche indicating the direction of Mecca, known as the qiblah.

Its construction formed part of Al-Mutawakkil’s wider building program, which helped transform Samarra from a medium-sized centre into a major city. Workers, artists, and architects were brought from across the Abbasid realm. Lists of building projects associate the mosque with as many as twenty palaces, whose combined cost was given as between 258 and 294 million dirhams.

Political upheaval and destruction

Al-Mutawakkil was assassinated in 861. Unrest followed, including a civil war in 865 and 866 and a broader decade of political troubles. These conditions made it difficult for later caliphs to undertake projects on a similar scale.

The mosque was destroyed during the thirteenth-century Mongol invasion of Iraq under Hulagu Khan and then fell out of use. Its outer wall and spiral minaret remained the principal identifiable elements of the complex.

Preservation and modern damage

An Iraqi preservation delegation was formed in 1936. Restoration involving the Iraqi State Organization of Antiquities, historians, and architects began in 1956, addressing the courtyard and the spiral minaret. Specialist repairs in 1970 treated moisture damage, replaced deteriorated bricks, repaired the main stairway, and restored the minaret’s upper arches and curves.

An explosion destroyed the top of the minaret in 2005. Iraqi insurgents may have been responsible, while United States forces had previously used the tower as a sniper position, leaving the circumstances uncertain. In 2015, UNESCO, the United Nations Educational, Scientific and Cultural Organization, and the Iraqi government announced a project to assess damage and restore the minaret and the wider archaeological site.

The mosque forms part of the Samarra Archaeological City, which entered the UNESCO World Heritage List in 2007. The archaeological city has also been treated as an endangered heritage property.

The mosque enclosure and prayer complex

Enclosure walls and entrances

The principal enclosure measured approximately 240 by 156 metres. A larger U-shaped enclosure, incorporating roofed extensions, measured about 443 by 375 metres and covered approximately 165,886 square metres. The mosque and its roofed extensions together covered about 66,468 square metres.

A baked-brick wall surrounded the main structure and was strengthened by forty-four semicircular towers. It contained twenty-eight windows, including twenty-four facing southeast toward the qiblah. There was one window for each aisle except at the mihrab. Sixteen doors opened through the enclosure, with six on the east, five on the west, two beside the mihrab on the south, and three on the north.

Courtyard and prayer hall

A large rectangular courtyard occupied the centre and was enclosed on all four sides by covered aisles or arcades. The plan contained seventeen aisles and nine internal passages, with four rows of porticoes around the courtyard. The prayer hall included a large arched mihrab and exceeded the prayer halls of many other mosques in size.

The roof stood approximately 11 metres above the floor and rested on 464 baked-brick pillars. Most were octagonal brick piers, while four imported marble columns marked the corners. Arches rested directly on plaster-covered mud-brick supports, and a continuous brick slab provided a substantial foundation for the columns. The interior was comparatively plain, giving prominence to the brick platform and colonnade.

Courtyard fountain and decoration

A large fountain stood at the centre of the courtyard. It was domed or covered and decorated with marble tiles and mosaics. Tradition held that it was carved from a single large stone called the Pharaoh’s Cup and transported by elephants. The fountain was attributed to Caliph Al-Wathiq.

Dark-blue glass mosaics or glazed panels in blue, white, and gold decorated the walls. Fragments of these panels were found within the mosque precinct. Interior stucco carving used floral and geometric designs regarded as an early form of Islamic decoration.

The Malwiya spiral minaret

Form and position

The Malwiya Tower, whose name refers to its twisted or spiral form, originally stood apart from the mosque and was connected to it by a bridge. Built of sandstone between approximately 848 and 852, it rises about 52 metres and measures approximately 33 metres across at its base. Its tapering spiral cone is encircled by an ascending ramp and stairway.

The minaret stands on the mosque’s central axis, about 27.30 metres from the northern wall. Its base comprises two square platforms. The lower platform measures approximately 31.30 metres on each side and is 2.5 metres high. The upper platform is approximately 30.10 metres long and 1.60 metres high. Together, they create a base 4.10 metres high with thirty-three niches.

Platforms and ascent

The lower platform had six doors on its southern side, facing the mosque’s northern wall, and nine doors on the other three sides. A former sloping brick stairway, approximately 25 metres long and 12 metres wide, connected the mosque’s northern wall with the upper platform and the beginning of the spiral ascent.

The spiral body was arranged in five progressively smaller levels, with stated heights of approximately 10.20, 8.12, 8.83, 8.10, and 5.40 metres. Above the fifth level stood a cylindrical structure with eight curved sections and pointed arches. The arches were approximately 2.25 metres high and between 1.10 and 1.15 metres wide. They were set within frames about 1.90 metres wide and 2.90 metres high, supported by cylindrical elements about 40 centimetres in diameter.

The spiral stairway contained 399 steps and rose around the five levels. Because of the circular plan and slope, individual steps varied in size, with stated dimensions ranging from approximately 2.5 metres by 57 centimetres to 1.90 metres by 65 centimetres. At the top, the stairway passed through a brick-vaulted entrance about 1.10 metres wide and 2.90 metres high before continuing up a further twenty-two steps to a highest point of approximately 50 metres.

Function and architectural influence

The minaret’s height made it suitable for the call to prayer, or adhan, and allowed it to be seen across the area around Samarra. It may also have served as a prominent visual statement of Islam in the Tigris Valley.

The tower’s spiral design has been linked with the ziggurat, a monumental stepped structure of ancient Mesopotamia, as well as with the Sasanian-period Pillar of Gor and other Sasanian spiral towers. The origin of the form remains debated. Some modern scholars have challenged or rejected a direct connection with ziggurats and instead proposed possible Sasanian influence.

The mosque’s design influenced later architecture. The Mosque of Ibn Tulun in Cairo drew on Samarra’s architecture and open layout, while the spiral minaret of the Abu Dulaf Mosque in Samarra repeated the type. The Malwiya’s spiral form also inspired Philip Johnson’s 1976 Chapel of Thanksgiving in Dallas and minarets associated with Sheikh Khalifa Mosque in Al Ain.

Surviving fabric

The outer wall and Malwiya remain the principal surviving elements of the Great Mosque. Before modern restoration, six steps remained in the minaret and very few complete arches survived around the courtyard. The upper portion of the minaret was partially destroyed by the 2005 explosion, while restoration and repair campaigns have addressed parts of the courtyard, stairway, brickwork, arches, and curves.
