During the Middle Ages, the focus of activities of the settlement was around the Thermisia lagoon with its famous salt mines, which today is a well-known wetland of the prefecture and a wet passage for rare migratory birds.
Today, the quiet little village of Thermisia has about 500 inhabitants, who are mainly engaged in agriculture, since the area is overrun with orchards of citrus trees, apricots and olives.
