Large Hadron Collider belongs to the Common Era — dated here to c. 2008 CE at Geneva region. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
A 27-km superconducting ring under the French–Swiss border — the largest machine ever built to smash particles.
How it amazes the brain
Magnets colder than space, detectors the size of buildings, and a global collaboration.
Why it counts as a wonder
It never needed a contest ballot to scramble the brain: scale, craft, or sheer improbability is enough.
A wonder you can’t see from a bus — but that found the Higgs boson.
On dating
CE means years after the traditional birth of Christ. A monument listed as c. 2008 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.
This is story 77 of 100 in The Trend Ledger’s illustrated desk on world wonders raised after the birth of Christ — the companions to our BCE series.
