The River Tronçon cuts a swathe through both Normandy and Brittany. Over the years, Saint-James has been much influenced by the areas surrounding it, both Norman and Breton. Granite from Louvigné du Désert in Brittany, for instance, was used for much of the construction across the canton. The geographic location of Saint-James, initially a military stronghold, has made it the centre of Breton-Norman interaction across the centuries. Today’s local fêtes preserve some of the traditional exchanges, such as the Normandy versus Brittany quoit throwing competition at Montjoie Saint Martin’s Apple and Chestnut fête, which is held every year to celebrate the first cider pressings.
Today’s world-famous brand Tricots Saint-James belongs to the town’s tradition of clothes manufacturing, a tradition which dates back to the Middle Ages, when there was already significant commercial activity across local and national boundaries. The famous sailor’s jersey was worn by navigators setting sail from Saint-Malo for England as well as for other countries.
