Serapeum sarcophagi weigh 100 tons, were all empty and remain unexplained. Serapeum contains massive sarcophagi weighing up to 100 tons each All 25+ sarcophagi were found completely empty with no inscriptions Stone cuts show 90-degree interior angles with precision unclear

At the Serapeum of Saqqara, archaeologists found massive sarcophagi weighing around 40 tonnes each (with lids weighing 25 tonnes) — all 25+ were empty with no human remains found. The precision of their 90-degree interior angles remains unexplained, and scoop marks on the stone are interpreted as crack prevention similar to aircraft aluminum repair. Internal surfaces are fully polished, no two sarcophagi are identical, and how they were transported and placed remains a mystery (1500-500 BC).
