The structure of the soil of the North Adriatic and the configuration with perpendicular affluent allowed for the formation of shallows that turned into salt pans throughout the centuries. While the Romans were supposedly the first producers of salt, the salt-pans of Northern Adriatic were the biggest and most important in Europe.
In the 13th century the Benedictine monks used brine and salt mud to cure obesity, dropsy, rheumatism, scrofulous and wounds. They had a detailed list of illnesses and their suitable treatments. It was only then that the first organized treatments with a definite methodology using natural factors from the salt-pans of the North Adriatic Sea actually started.
The first written records of treatments with brine of Northern Adriatic date to the 12th century. It is nonetheless of considerable importance what bishop Tomasini noted in 1650: "In Northern Adriatic Sea there are salt pans with curative mud and brine. On their pilgrimage to the church of St.Laurence , the pilgrims cover parts of their bodies with mud, then warm themselves under the sun and finally bathe in the saline water - Brine. This way they cured rheumatism and skin diseases." (Kandler, 1879)
For centuries, salt-pans were the important part of the economy. Salt was a precious raw material and a strategic merchant commodity. At present only these salt pans are still preserved.
The salt-pans of Northern Adriatic are peerless in producing healing substances such as brine water and therapeutic salt mud due to their specific soil structure, saturated with minerals and combined with the unique cultivation and crystallization. The traditional, organic method of extracting salt makes these salt-pans unique in the world.
