Great Stupa of Sanchi belongs to the years before the Common Era — dated here to c. 250 BCE at Sanchi, India. The date is a scholarly centre of gravity, not a foundation-stone timestamp.
Ashoka’s brick mound, later cased in stone, with four toranas carved as a stone picture-book of the Buddha’s lives — without showing his face.
How it was made
A hemispherical anda, harmika, and circumambulatory path. The gateways are the wonder within the wonder.
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 among the oldest standing Buddhist monuments. Aniconic and crowded with stories at once.
On dating
BCE in this series means years before the traditional birth of Christ, counted backward. A monument listed as c. 250 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.
