In the 11th century, the honey-coloured French limestone used in Sussex may well have come from quarries beneath the centre of the town of Caen itself. William of Normandy had his own quarry at the foot of his castle in the town. Other quarries opened and closed over the centuries.
Today there are over 250 hectares (600 acres) of mined galleries beneath the streets of Caen and its suburbs. In a somewhat unpatriotic statement, an inhabitant of the town has compared the area to a certain Swiss cheese: Le sous-sol de Caen est devenu un véritable gruyère constellé d’anciennes carrières. [Underground Caen has become a veritable gruyere cheese, with its constellation of ancient quarries.]
