The river of the Marca
Sile originated from several resurgent rivers and it flows with a certain windingness from west to east. Once it has traversed Treviso, it curves towards the south-east in the direction of the Venetian Lagoon. In 1683, the Most Serene Republic diverted the water flow through the Taglio del Sile canal, which transferred the waters onto the old bed of the Piave, which in turn had been diverted. There are many windmills along its banks which generated very important activity for the land. The entire course of the river is protected by the regional Natural Park of the River Sile. It meets the sea between Lido di Jesolo and the Cavallino coastline (in the harbour of Piave Vecchia).
