The history of the town, built near to tributary stream, goes back to Roman times.
Now it is in the centre of a wide expanse of agricultural land. Between the nearby Ferrara waterway and the canals in the reclaimed land are the Anse Vallive - Po Delta Park, which are ideal for bird-watching, fishing, cycling and other outdoor pursuits.
They constitute the only remains of the former marshes that once surrounded the village, saved from the most recent reclamation of the Valle del Mezzano and set up as an 'Animal Sanctuary'.
The four marshy coves constitute a freshwater wetland biotope, which is distinctive and unique in the Ferrarese lowland territory, above all for the quantity and variety of animals that populate it.
There are no less than 150 species of aquatic birds that nest or visit.
