The Cornia is a 49 km long river in Tuscany that runs through the provinces of Pisa , Grosseto and Livorno from north to south-west and flows east of Piombino in the Arcipelago Toscano into the Tyrrhenian Sea .

course

The Cornia rises on the Monte Aia dei Diavoli (875 m) a few hundred meters north of Sasso Pisano , a district of Castelnuovo di Val di Cecina , where it spends a total of 8 km in the municipality and where after the district of Leccia the Turbone (20 km total length ) from the municipal area of Pomarance from the right. From here it moves first to the west and then to the southwest to form the municipal boundary with Pomarance (2 km in the municipality) and then Monteverdi Marittimo (2 km in the municipality). It then represents the border between the municipalities of Monteverdi Marittimo ( Province of Pisa ) and Monterotondo Marittimo ( Province of Grosseto , 9 km in the municipality) and later that of Suvereto , passing from the Province of Grosseto to the Province of Livorno . When entering the northern municipality of Suvereto, the river receives the waters of the 12 km long Torrente Massera from the right , then later after the bridge Ponte delle due Province from the left the Torrente Milia (20 km total length). In the municipality of Suvereto, the river remains a total of 13 km. After Suvereto, the Cornia flows through the municipality of Campiglia Marittima (9 km). The river enters the Tyrrhenian Sea east of Piombino (6 km in the municipality) .

The estuary is divided into two rivers. These are divided between Venturina (11 m, district of Campiglia Marittima) and Colmata (2 m, district of Piombino). The smaller and original part, called Cornia Vecchio , flows further south-west here and flows to the Ponte d'Oro near the port of Piombino. The larger part is the Cornia canalizzata , it turns south and flows into the Tyrrhenian Sea near the Torre del Sale (salt tower, built in 1830) and the building called Casa del Sale from the 17th century near the ancient salt mines mentioned in 1094.

history

The first attempts to drain the marshes in the area of ​​the estuary, called Padule di Caldana (today near today's Venturina), took place in the middle of the 16th century under Cosimo I de 'Medici . The first dams were built here. However, the work was only continued under Leopold II in the 19th century, when Leopold II . November 1828 ordered the continuation of the work by decree. Work to fill the Padule di Piombino began in 1832, and more dams were built at the beginning of the 20th century. The current course of the Cornia canalizzata with its influence into the sea at Torre del Sale was completed in 1957.

Val di Cornia

The Cornia Valley (Val di Cornia) also includes municipalities through which the river does not flow. These include San Vincenzo and Sassetta (both in the province of Livorno). In the north the Cornia valley borders on the Colline Metallifere and the Cecina valley , in the east on the Maremma and in the west on the Etruscan Riviera (Etruscan Coast - Costa degli Etruschi).
