The Great Mosque of Djenné is the largest mud-brick structure in the world, and it is also one of the most fragile - a sculpture of sun-baked earth that would dissolve back into the floodplain within a few seasons if the people of Djenné ever stopped caring for it. They have not stopped in over a century. The plaster smeared across its walls each April is the same color as the riverbank it came from, and the men who climb the wooden scaffolding to apply it are often the grandsons of the men who climbed it before.

The crépissage is a community replastering, and in Djenné people will tell you it matters more than the great religious holidays. For days beforehand, the plaster cures in pits, where young boys are sent to wade and stomp through the m...

A mosque stood here as early as the thirteenth century, but by the time René Caillié reached Djenné in 1828 it had been left to ruin, abandoned to nesting swallows after the Fulani leader Seku Amadu let it decay. The rebuilding came in 1907, c...
