complex comprising four principal basins, The Valle Lido di Magnavacca, the Valle Fossa di Porto, the Valle Campo and the Valle Fattibello, and several smaller ones. Approximately ten kilometres to the north, also in the territory of

, is the Valle di Bertuzzi. The lagoon was formed around the tenth century due to subsidence of the soil and silting of the coastal zone. At the time of formation, the area was flooded with fresh water from the recurrent flooding of the rivers. From the sixteenth century on, they gradually were filled with sea water resulting in the modern appearance of brackish water-filled basins. The original extent of the Valli di Comacchio – covering about 73,000 hectares – was progressively reduced as a result of various

Points of interest

Fishing is a common occupation: in fact there are still many fishing settlements in the area today. Typical of the area are fishing lodges mounted on poles in the water. These structures serve both as fishing stations and places to monitor for illegal fishing. Also common are eel-fishing basins called ''lavorieri''. There are numerous salt-panning facilities in the area.
