Red Pyramid of Dahshur belongs to the years before the Common Era — dated here to c. 2575 BCE at Dahshur, Egypt. The date is a scholarly centre of gravity, not a foundation-stone timestamp.
Sneferu’s last pyramid is the first successful smooth-sided royal tomb, named for the rusty local limestone of its exposed core.
How it was made
The 43-degree slope is conservative after the Bent Pyramid. Corbelled chambers rise like tents of stone inside.
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.
Tourists still walk the corridors. Architecturally it is Giza’s dress rehearsal.
On dating
BCE in this series means years before the traditional birth of Christ, counted backward. A monument listed as c. 2575 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.
