Stone and crew in numbers
- Country and type
- France, cathedral
- Stone in the walls
- 55,000 to 90,000 m³ Estimate
- For comparison
- about 29 Olympic pools of stone, or 7,250 truckloads
- Average crew

Volume basis: 130 m long; nave 16.4 m wide, 37 m high; transept 64 m. Checked against measurements. Our estimates come from published dimensions and are shown as a range. The result is a simple model, not a measured fact.
Where the stone came from

Legend: tradition, not evidence
The tunic of the Virgin Mary kept at Chartres, the Sancta Camisia, is said to be a gift from Charlemagne.
What we know: Historians doubt it, since Charlemagne never went to the Holy Land. The relic still made Chartres a pilgrimage town.
