Quarrymen dug the catacombs tunnels, selling the limestone and gypsum to construct buildings, roads, sculptures and bridges. The Romans were the first to quarry the rock and used the stone to build bathhouses and the arena found on the Île de la Cité. Later, quarry stone would be used to construct the Louvre and Notre Dame.
