Temple of Jupiter Optimus Maximus belongs to the years before the Common Era — dated here to c. 509 BCE at Capitoline Hill, Rome. The date is a scholarly centre of gravity, not a foundation-stone timestamp.
The Republic’s foundation-year temple to the Capitoline triad, the largest in central Italy, with Etruscan artisans and terracotta sculpture.
How it was made
A high podium, three cellae, and a painted terracotta quadriga. Rebuilt after fires, it set the template for Roman state religion.
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.
Palazzo architecture sits on the bones. The wonder is political: a temple as a constitution in masonry.
On dating
BCE in this series means years before the traditional birth of Christ, counted backward. A monument listed as c. 509 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.
