Cave di granito di Cala Francese

These ancient granite quarries at Cala Francese give you a rare look at Sardinia's industrial past set against a stunning coastal backdrop. The site includes a museum housed in a former quarry shed, packed with original machinery, photos, and documents that tell the story of the workers who shaped this landscape. It's a surprisingly moving place — raw stonework, hammock-smooth granite formations, and sheltered seaside calm all rolled into one.
