The salt industry at Figuera de la Foz, a seaport and resort on the Mondego estuary, dates from the eleventh century AD, but many of the traditional salinas are being converted to fish farms. The salt pans in the region are characteristic of those on Atlantic coasts where the tidal range is much greater than in the Mediterranean or the Black Sea. Much of the salt they produced was used in the preservation of cod. Developments during the ALAS (All about Salt) project at Figuera de la Foz included the restoration of a whole salina, the Corredore de Cobra, the reconstruction of a traditional salt warehouse, and the establishment of a salt museum.
