The production of salt in Touques goes truly back to the XIIIth century. At the time, there were 52 salt marshes, which made Touques the main production site of salt along with Mount St-Michel.
In Normandy to produce salt, a very special process had to be used; it goes as follows: the first process consisted in pourring frech water into large vats in which a layer of sand had been laid over a layer of straw. The water got soaked with the salt from the sand. This "brown" water is then transfered into another vat called "lead" which is heated during about two hours. Once all the water is evaporated, the salt is placed into conical shaped wicker baskets.
Once so prepared, this salt is stocked into granaries. Unfortunately, Touques salt, although of a remarcable quality, does not keep well. In 1656, the number of salt marshes dropped to 24. The "saulniers" (salt workers) became rare and a certain number of them left the town for far away countries... as did Nicolas Bellenger known as the "Saulnier", who left for Canada .(A publication of the town of Touques 2000, page 10)
