From swamp to Palù
The marsh of the sources of Livenza was formed in a structural natural depression , bounded to the east by the Col Longone , to the west by the slopes of Cansiglio and crossed to the north by gravels transported by Gorgazzo river.
At the base of the mountain range Cansiglio / Cavallo, from which they are derived, are aligned on a range of 5 km he three perennial springs of Livenza river: Gorgazzo (north-west), Santissima (in the village of Polcenigo) and Molinetto (in the village of Caneva ).
We have a pool of water with fluctuating heights since prehistoric times, that in the last two centuries was subjected to various reclamation and plumbing works (excavation of ditches, canals, draining, the construction of a canal that runs through Col Longone for the supply of a power plant) that partially altered the natural moist environment. Despite the introduction of these changes, we still have a stratified deposit of extraordinary importance for prehistoric archeology and for the study of environmental change over the past 15,000 years.
