The damage from the earthquake that struck Morocco on Sept. 8, 2023, is still being assessed. Moroccans are grappling not just with the loss of thousands of lives, but also with the widespread destruction of their cultural heritage and historical sites.

Among them is a 12th-century mosque in the village of Tinmel, about 4 miles from the epicenter of the quake that flattened many of the villages in the Atlas Mountains.

The mosque at Tinmel was originally built to commemorate the figure of Ibn Tumart, founder of the Almohad movement that ruled an empire stretching from Mali to Spain from 1147 to 1269. Ibn Tumart was a Muslim reformist who advocated for greater accessibility and clarity in Islamic law and scripture. The Atlas tribes spoke little Arabic and lived in remote villages, so Ibn Tumart translated the Quran into the vernacular and issued the call to prayer in the local Berber dialect.

After Ibn Tumart’s death, his tomb at Tinmel became a shrine, marked by a simple whitewashed dome in front of the mosque. Under the Almohads, Ibn Tumart was venerated as a saint, and the early Almohad caliphs were also buried alongside him, turning Tinmel into a potent site of spiritual and social memory.

As an architectural historian who specializes in medieval Morocco, I have spent many years visiting and researching Tinmel. For nearly 900 years, Tinmel was central to a distinctly Moroccan Islamic tradition, but the events of the past week have thrown its future into doubt.

Built in 1148 by Ibn Tumart’s successor, Abd al-Muʾmin, the mosque embodied the core principles of Almohad architecture. A rectangular prayer hall was supported by plaster-coated piers, while a façade of geometric ornamentation emphasized the niche that indicated the direction of prayer, the mihrab.

The structure was designed to encourage circumambulation around the mosque, with the ornamental decoration intensifying the experience. The closer one moved toward the mihrab, the more elaborate the design became, drawing the eye of the viewer in.

But the mosque’s most unusual element was its minaret, which wrapped around the exterior of the mihrab. A staircase behind the niche led to the upper story of the structure, where the call to prayer could be issued out over the valley.

Historically, minarets were never constructed in conjunction with the mihrab, but off to the side or opposite the mihrab. Tinmel’s minaret was thus both unique and innovative.

Positioned on a steep hillside, with the mihrab and the minaret both facing the slope down toward the seasonal stream known as the Wadi N'Fiss, the mosque and its shrine looked larger and more monumental than their physical size suggested.
