About

Quarries on the southern slopes of Monte Capanne, above the village of San Piero, produced a coarse gray granite that Roman workers cut into columns, basins, and sarcophagi for shipment to the Italian mainland. The Roman era marked the most intensive period of extraction across the island's granite deposits, which stretched along the coast from San Piero to Pomonte. Half-finished columns and altars still lie scattered among the quarry faces, abandoned mid-cut. A marked trail today follows the routes quarry workers once used to move blocks down toward the shore.

What happened here

The rock is worked in benches from the top down, so that gravity does the moving. Channels are cut around a block with a pick, then it is split from the bed with iron wedges driven into a line of holes, sometimes with wooden wedges soaked to swell. Blocks are dressed roughly on the spot — no one hauls waste — and marked with the quarry, the gang, the date and the consular year, which is how the empire keeps track of what it owns. Sledges, rollers and ox teams take them to a river or the sea, because moving stone overland is the expensive part. Fine marbles are imperial monopolies. Abandoned faces still show the last unfinished cut, stopped mid-job and never resumed.
