Clairmarais owes its origin to the famous Cistercian abbey founded by St. Bernard in 1140. He gave the village the name of Claromarisco (later to be Clarus Mariscus and then Clermarez) because of the huge marshes and many rivers in the vicinity. The Dutch Klaarmares and West Flemish Cleremeersch names reflect the nature of the terrain, too. Clairmarais became a fully-fledged common in 1790 when the abbey was going to be destroyed and sold as a national asset during the French Revolution.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
