Salina di Comacchio

Within the Po Delta park, the Comacchio Salt Pans preserve the layout shaped by Napoleonic engineers: evaporation basins where salt production ran from 1810 until 1984. The former industrial landscape is now a wetland inhabited by flamingos, avocets and terns.

Why it matters

Salt shaped Comacchio's economy and history. Trading in it earned the town a treaty with Lombard king Liutprand in 715, while Venice burned the town and its pans in 932 amid its defense of a salt monopoly. The present basins took their form in the Napoleonic era, and production continued until 1984. After the works closed, the site became a wetland supporting plants, invertebrates and birdlife. A LIFE Natura project from 2000 to 2005 began ecological recovery; the salt pans now form part of a UNESCO MAB biosphere reserve within the Po Delta park.

What to notice

Long embankments divide shallow basins whose colours shift from green to rose with salinity. Windmills, nets and salt piles recall the former industry. The Torre Rossa, a sixteenth-century star-shaped fort, now serves as a bird-observation structure, while screening hides provide views of the avifauna. The prodina regulates water levels between basins. The salinetta is a four-hectare miniature salt pan where staff continue to rake salt by hand using traditional tools. Birds recorded in the wetlands include flamingos, avocets, black-winged stilts, terns, gulls and herons.

Context and history

The salt story predates the present basins: Etruscan Spina traded along a salt route between the sixth and fourth centuries BC, although certain traces of pre-Roman production have not survived. In 1598, as Este rule ended, Pope Clement VIII authorised salt making in the Comacchio valleys; production later revived under the Papal States. Napoleon's government rebuilt the works in 1808 to a French multi-harvest design drafted by engineer Gerard de Bayon on 523 hectares of donated valley land, with construction carried out largely by more than three thousand soldiers. The Congress of Vienna returned the site to the Papal States, and the state assumed direct management in 1882. A community of salt workers lived among houses, a church and meeting places. Mechanisation after the 1960s consolidated many basins into eight large ones; production ended in 1984, followed by a ministerial decree formally closing the salina in 1985.
