The area currently known as the Diaccia Botrona Nature Reserve once contained a saltwater basin connected to the sea, which for centuries provided a significant economic source, ensuring the livelihood of the surrounding areas thanks to fishing, the fish trade, and the supply of salt. This enormous "piscaria" or fishpond, on which the castle stood, later became the toponym of the town, called Castiglione della Pescaia. Over the centuries, the Prile initially lost its salinity (the lake was declared a freshwater pond in 1386) and then gradually dried up, forming the marshy basins that characterize the wetland.
