Great Mosque of Djenné belongs to the Common Era — dated here to c. 1907 CE at Mali. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
The largest mud-brick building on Earth — replastered yearly in a communal festival.
How it amazes the brain
Adobe with palm-wood torons as scaffolding forever embedded. Sudanese-Sahelian style at its peak.
Why it counts as a wonder
It never needed a contest ballot to scramble the brain: scale, craft, or sheer improbability is enough.
A living wonder: the maintenance is the monument.
On dating
CE means years after the traditional birth of Christ. A monument listed as c. 1907 CE may have been founded earlier, rebuilt later, or become famous only in one phase. Engineering wonders (dams, tunnels, orbiting labs) are dated to opening or assembly.
