Mesa Verde cliff dwellings belongs to the Common Era — dated here to c. 1200 CE at Colorado, USA. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
Ancestral Puebloan apartments tucked under sandstone alcoves — cities that hang in cliffs.
How it amazes the brain
Sandstone masonry, kivas, and farming on the mesa top with dwellings in the shade below.
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. 1200 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.
