Back in the old days, salt was taken directly from the sea, using progressively shallower pools where the salt becomes more concentrated as the water evaporates. The job is a tough one, as the salt needs to be scraped off the cement pool floors everyday. This picture is showing the last stages, where the salt gets split into piles and put in a warehouse. It was a great experience in a beautiful Croatian village called Ston, north of Dubrovnik. Unfortunately, these traditional activities are not used often anymore.
