Empire State Building belongs to the Common Era — dated here to c. 1931 CE at New York, USA. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
Raised in 13 months during the Depression — Art Deco steel that held the “world’s tallest” crown for ~40 years.
How it amazes the brain
Riveted steel frame, setbacks for light and air laws, and a mooring mast that never became a regular airship dock.
Why it counts as a wonder
It never needed a contest ballot to scramble the brain: scale, craft, or sheer improbability is enough.
Still the textbook of how to assemble a city in the sky, fast.
On dating
CE means years after the traditional birth of Christ. A monument listed as c. 1931 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.
