It is on the southern part of the Quiberon peninsula, the northern part being the commune of Saint-Pierre-Quiberon. It is primarily known as a seaside resort for French tourists during summer, and for its history of sardine production. Quiberon is connected to the mainland by a tombolo.
In the 19th century, Nicolas Appert, a chemist, developed a technique that permitted the sterilization of food. Thanks to this process, Quiberon became the leading harbour for sardine fishing and the production of canned sardines in France. Many families from the Finistèredépartement migrated to Quiberon for the fishing season (May to October). When the men put out to sea, the women worked in the sardine can factories.
The railway between Auray and Quiberon was inaugurated in 1882. It deeply changed Quiberon’s way of life. Fishing, canning and the exploitation of seaweed has been replaced by tourism. At that time, Quiberon became a favoured destination for the famous, including the writers Gustave Flaubert and Anatole France, and the actress Sarah Bernhardt. The year 1924 was important for the peninsula because it was classified as health resort. Now, the main resources for Quiberon come from tourism.
During the Second World War, Penthièvre Fort at the narrow isthmus was occupied by the Germans and incorporated into the Atlantic Wall. It housed various blockhouses, but was mainly used by the infantry. In July 1944, 59 resistance fighters were tortured and buried alive there. A Cross of Lorraine mounted on a stone pillar, with a plaque listing the names of the fighters, stands in their memory. Although the fort is still of military importance (as a training base), a gallery (tunnel) where the bodies were discovered can be visited.
