Bordering the ocean, the pretty little town of Quiberon, with its opulent seafront houses, is reputed to be the historic Breton stronghold of the sardine fishing and trade. In the 19th century, when Nicolas Appert made the revolutionary discovery of sterilising food by heat, known as "appertised canning", the town became France's leading sardine port and created a multitude of sardine factories in the Port-Maria district. Many families from all over Brittany moved to Quiberon to take advantage of this new industrial boom.
