Salinas de Poza de la Sal, Salt evaporation ponds in Poza de la Sal, Spain.
Salinas de Poza de la Sal is a salt production site nestled in a wide depression on the eastern side of Páramo de Masa, featuring a network of evaporation pools, water channels, and storage buildings. The terrain descends from approximately 1,100 meters to 650 meters in elevation, preserving the physical remains of centuries-old salt extraction infrastructure.
Documentary records from the 10th century first mention these salt flats, marking the beginning of their exploitation as a major production center. Over subsequent centuries, the site expanded with new infrastructure, including royal warehouses that reflected its economic importance to the region.
Salt production here followed a traditional pattern that shaped local life and identity for generations. The work brought together families and workers who understood the seasonal rhythms of water flow and evaporation as part of their daily knowledge.
The site can be explored on foot with informative signs throughout explaining the remaining buildings and structures. Visiting during dry weather is advisable since the terrain can be damp in certain areas due to water channels and natural springs.
The geological origins of this site stretch back 240 million years to the Triassic period, when an ancient lake dried up and left behind salt layers approximately 500 meters thick. This ancient foundation remains hidden beneath the surface but continues to influence how water and minerals behave at the site today.
