Beijing Water Cube belongs to the Common Era — dated here to c. 2008 CE at Beijing, China. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.
ETFE bubbles cladding a swimming cube — soap-foam geometry as architecture.
How it amazes the brain
Space-frame structure with pneumatic pillows lit in colour at night.
Why it counts as a wonder
It never needed a contest ballot to scramble the brain: scale, craft, or sheer improbability is enough.
Later converted partly into a waterpark — Olympic wonder with a second life.
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.
