Stone and crew in numbers

Country and type
France, cathedral
Stone in the walls
55,000 to 85,000 m³ Estimate
For comparison
about 28 Olympic pools of stone, or 7,000 truckloads
Average crew
about 32 workers (model value: the crew that would need exactly this long, working without a break)

Volume basis: 112 m long; vault 32 m; tower 142 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

Pink Vosges sandstone. The oldest parts use hard, coarse Vosges sandstone, probably from the Mossig valley near Wasselonne. Later work uses finer sandstone from quarries at Wasselonne and Dinsheim, worked from the 13th century.

Legend: tradition, not evidence

Sabina von Steinbach, the daughter of master builder Erwin, carved the famous statues of the south portal.

What we know: The story arose in the 19th century from a lost inscription naming "Savinae". The Catholic Encyclopedia says it rests on a mistaken reading of a scroll.
