A salt pan is a place where saltwater is left to evaporate naturally until only salt remains. The salt is then collected for consumption and trade.
There are two main types of salt pans: coastal salt pans, which use seawater, and inland salt pans, which rely on naturally occurring salt springs fed by underground salt deposits.
Long before the arrival of the Romans, the first inhabitants of these shores already understood the value of salt. When hunting or fishing was scarce, they evaporated seawater to obtain salt and preserve food, ensuring survival during difficult periods.
## The Roman Empire and the Rise of Salt
With the arrival of the Romans, salt production expanded significantly. Salt was essential for preserving fish and meat, but also for producing one of the most prized foods of the Roman world: garum.
Garum was a fermented sauce made from oily fish, salt, aromatic herbs, oil, vinegar, or wine. Considered a luxury delicacy, it was exported throughout the Empire.
The Romans are also credited with building Galicia’s first organised salt pans, usually located within the sheltered estuaries. Archaeological remains of Roman salt works can still be found along the Galician coast today.
## Salt Trade and the Royal Warehouses
During the Middle Ages, salt became a strategic resource. At the beginning of the 14th century, it became a Royal monopoly, managed through a network of official salt warehouses known as *alfolíes*.
Galicia's production, however, was insufficient to meet the growing demands of the fishing industry. The region’s climate, with relatively few sunny days, limited large-scale production, making imports from Andalusia and Portugal necessary for centuries.
Even so, local salt production continued until the late 18th century and remained closely linked to Galicia’s maritime economy.
## White Gold
Salt became so valuable that it earned the nickname “White Gold”.
Far more than a seasoning, salt preserved food, supported trade routes, powered economies and became the subject of taxes, monopolies and even wars.
One of the most famous events in the history of salt took place in India. In 1930, Mahatma Gandhi led the historic Salt March, a peaceful protest against the British monopoly that prevented Indians from producing their own salt.
For almost a month, thousands of people walked with Gandhi to the sea in an act of civil disobedience that became one of the defining symbols of non-violent resistance in the 20th century.
The story of salt is, ultimately, the story of humanity’s relationship with one of the sea’s most precious gifts.
