Treasury of Atreus belongs to the years before the Common Era — dated here to c. 1250 BCE at Mycenae. The date is a scholarly centre of gravity, not a foundation-stone timestamp.
A tholos tomb with a 14.5-metre corbelled dome, the largest spanning space in the world for over a thousand years.
How it was made
A dromos of ashlar, a 120-tonne lintel, and a vanished decorative façade of coloured stone.
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 pyramid turned inside-out: a wonder of interior sky.
On dating
BCE in this series means years before the traditional birth of Christ, counted backward. A monument listed as c. 1250 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.
