Sultan Ahmed Blue Mosque belongs to the Common Era — dated here to c. 1616 CE at Istanbul, Türkiye. Dates mark a scholarly centre of gravity (dedication, completion, or iconic phase), not a single foundation day.

How it amazes the brain
Sedefkar Mehmed Agha’s plan balances a huge courtyard with a prayer hall of light.
Why it counts as a wonder

On dating
CE means years after the traditional birth of Christ. A monument listed as c. 1616 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.
