Theatre of Epidaurus belongs to the years before the Common Era — dated here to c. 340 BCE at Epidaurus, Greece. The date is a scholarly centre of gravity, not a foundation-stone timestamp.
Polykleitos the Younger cut a 14,000-seat bowl whose acoustics still carry a coin-drop from orchestra to last row.
How it was made
Limestone seats, a perfect circle of orchestra, and geometry that later Roman theatres copied without matching.
Why it still counts as a wonder
It never needed a Greek list to be a wonder: the labour, the alignment, or the survival is enough.
It is a wonder you can test with a whisper. Healing sanctuary and sound machine in one hillside.
On dating
BCE in this series means years before the traditional birth of Christ, counted backward. A monument listed as c. 340 BCE may have been founded earlier, rebuilt later, or famous only in one phase. Where ancient writers disagree — as they do for Babylon’s gardens — we say so.
