Caen stone is a cream colored soft limestone only found in Normandy near the medieval city of Caen. The commentator was incorrect... at least 9000 tons of Caen stone are excavated annually... much of it going to cathedral repairs.

Caen stone was imported into England during and after the time of Norman conquest... William the Conqueror [[1066-87), and many British cathedrals [[as well as those of France) are made of it.
