Great Mosque of Djenné
Djenné, Mopti region, Mali
The Great Mosque of Djenné, the current building completed in 1907 and widely described as the largest mud-brick building in the world, is the living heart of a Niger Delta town UNESCO inscribed in 1988 and repaired every year by the whole community in the Crépissage festival.
The mosque standing today is the third on the site: according to local tradition the first Great Mosque was raised in the 13th century by King Koi Konboro, Djenné's twenty-sixth ruler and its first Muslim sultan; a rebuilding followed in 1834-36; and the present structure was completed in 1907. Who built the 1907 mosque is itself a documented debate. Some scholars once argued the French colonial administration built it, but no colonial documents support that, and newer scholarship attributes it to Djenné's masons' guild, the barey ton, working alongside laborers including enslaved people brought by French colonial authorities. The mosque is built of sun-dried mud bricks (banco) over palm timbers (toron) and must be replastered annually before the rains, a community obligation carried out in the Crépissage festival, in which young men race up the toron with baskets of mud and women bring water from the river to mix the plaster. UNESCO inscribed the Old Towns of Djenné on the World Heritage List in 1988.
The mosque's interior has long been closed to non-Muslims, a restriction widely reported and not recent, and the town's situation has worsened with Mali's conflict: AP reported in 2025 that Djenné sits in a region affected by militancy and a collapse in tourism, and the Old Towns of Djenné have been on the List of World Heritage in Danger since 2016. A US State Department advisory of January 9, 2026 rates Mali Level 4: Do Not Travel. The honest entry says plainly that the mosque is effectively unreachable for most readers right now, while remaining one of the most significant living sacred buildings anywhere.
Visiting
The UNESCO World Heritage listing for the Old Towns of Djenné is the reference of record. Practically: Mali is rated Level 4, Do Not Travel, by the US State Department (January 2026), there is no meaningful visitor infrastructure, and the mosque interior is reserved for Muslim worship. This entry points readers to the Crépissage and the town's scholarship rather than to trip planning.
