On the flood plain of the Niger River in Mali stands the largest earthen building on the planet: the Great Mosque of Djenne. Built entirely of sun-dried mud, it is the masterpiece of Sahelian architecture and one of the most striking mosques anywhere, proof that grandeur needs neither marble nor gold, only earth, palm wood and the hands of a whole community.
Architecture of earth
The mosque is made from banco, a mixture of clay and straw shaped into sun-dried bricks and coated in smooth mud plaster. Its massive walls, some of them very thick, keep the interior cool through the fierce heat of the day and warm through the desert night. Three tall towers rise from the eastern Qibla wall, each capped with an ostrich egg, a local symbol of fertility and purity. The most distinctive feature is the bristle of wooden beams, called toron, that project from every face of the building. These are not only decorative: they are permanent scaffolding, the footholds workers use to reach the upper walls during repairs. This is a wholly different branch of Mosque architecture styles around the world from the domes of Istanbul or the arches of Cordoba, shaped by local materials and climate.
The annual replastering
Because it is made of earth, the mosque is worn down each year by sun and by the seasonal rains. So once a year, before the wet season, the people of Djenne come together to reface it in a celebrated festival. Men carry fresh mud plaster and climb the toron to smooth it over the walls; women and girls bring water; musicians play and the whole town takes part. In a single joyful day the mosque is made new. This yearly act of maintenance is also an act of belonging, and it embodies the historic idea, explored in short history of mosques, that the great mosque is the shared heart of its town.
A centre of learning
Djenne, together with nearby Timbuktu, was for centuries a hub of trade and Islamic scholarship in West Africa. Caravans crossing the Sahara carried gold, salt, books and ideas, and the mosque stood at the centre of a town famous for its teachers and libraries. The present building dates from 1907, raised in the old style on the site of a much earlier mosque that had stood since around the thirteenth century. The old town of Djenne is recognised as a UNESCO World Heritage Site.
A world away, the same faith
Set beside the Great Mosque of Damascus (Umayyad Mosque) or the Badshahi Mosque, Lahore, Djenne looks like it belongs to another planet, yet it serves exactly the same purpose: a hall turned toward Mecca where a community gathers to pray. That unity across such difference is the theme of our pillar on Great mosques of the world. Terms such as Qibla and minaret are explained in the Glossary.
Visiting
The Great Mosque is the pride of Djenne and the focus of its life, though in recent years non-Muslims have generally not been admitted inside; the exterior and the lively Monday market around it remain unforgettable.
