Like ancient fortifications, old salt prospection sites, like in Gerri de la Sal, are as varied and ingenious as local conditions made them. Tools and methods gave way to specialisation and professions bygone. We gaze at those old artifacts in museums today.
Yet in some cases those sites resist oblivion. One could believe their products have special properties that make them better than industrial offerings, and it may as well be. However the biggest contribution of those products is the promise of sustainability for small communities that otherwise would be displaced by the economies of scale of industry. Challenging global commodity prices, they send us a message of resilience and ingenuity.
