Argaçosa: The Sargassum (seaweed) and Salt

The name Argaçosa derived from argaço (seaweed, algae) denoting the importance of harvesting seaweed in this site. Both the harvesting of seaweed and the production of salt were possible due to the entrance of sea water in this area of the estuary of the Lima River before it gradually silted up.

There are numerous references to the salt pans or cortes (fractions of salt pans) found in the parish of Meadela, in the Inquisitions of 1258. The production of salt was an important economic activity in this village until the 18th century.
