Gateway Arch belongs to the Common Era — dated here to c. 1965 CE at St. Louis, USA. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
A 192-metre stainless-steel catenary arch — the tallest arch on Earth.
How it amazes the brain
Triangular sections stacked with creeping precision; a tram rides inside to the top.
Why it counts as a wonder
It never needed a contest ballot to scramble the brain: scale, craft, or sheer improbability is enough.
Minimal form, maximal wow.
On dating
CE means years after the traditional birth of Christ. A monument listed as c. 1965 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.
