In the 27th century BC, the Third Dynasty king Netjerikhet commissioned the first monumental stone building in Egypt, yet history knows him as Djoser, a name New Kingdom visitors scratched into his monument more than a thousand years later. His architect Imhotep was later deified by the Greeks as a god of medicine and healing. Until then Egyptian royals were buried in mud brick, and switching to stone meant copper mining expeditions into the Sinai, grain taxation, storehouses, boats, and thousands of fed laborers, forcing a centralized state into being. Djoser moved the royal burial ground from Abydos north to Saqqara near the capital, Memphis. His reign lasted either 19 years or nearly four decades, depending on how often the cattle counts were taken.

The Step Pyramid began as a square mastaba of local limestone cased in fine white Tura limestone and grew through repeated expansions into six steps 62.5 meters high, holding over 330,000 cubic meters of stone. Scholars still debate why: Rainer Stadelmann points to the square base, while Jean-Philippe Lauer argued the height was needed so the tomb could be seen over its perimeter wall. The complex, recently reopened after a 14 year restoration, served as an eternal palace.

• Accretion layers leaning inward at roughly 74 degrees so the stone mass would not blow out
• A wall over a mile long with 1,680 niches and 15 bastions, 14 of them fake doors for the king’s ka
• Stone columns carved as bundled reeds, the Heb Sed Court of dummy chapels, and a serdab statue peering north
• Six kilometers of tunnels below a 28 meter shaft holding over 40,000 stone vessels of First and Second Dynasty kings
• The South Tomb’s pink granite vault, too small for a body, and walls of blue faience tiles imitating reed mats
