Sydney Harbour Bridge belongs to the Common Era — dated here to c. 1932 CE at Sydney, Australia. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
The “coathanger” steel arch — climbed by tourists, carrying trains, cars, and bikes across the harbour.
How it amazes the brain
Half-arches built from each shore met mid-span. Riveted steel on a heroic scale.
Why it counts as a wonder
It never needed a contest ballot to scramble the brain: scale, craft, or sheer improbability is enough.

On dating
CE means years after the traditional birth of Christ. A monument listed as c. 1932 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.
