Ru irrigui di Sarre
The ru of Sarre are traditional irrigation channels that carry water from mountain streams across the slopes and fields above the Dora Baltea.
Why it matters
These channels are both agricultural infrastructure and part of the region's cultural landscape. Their construction, upkeep and shared use helped sustain farming communities and shaped the cultivated slopes of the Aosta Valley. Sarre's network includes channels such as the ru de Ville-sur-Sarre and the ru de la Doire.
What to notice
The network adapts to varied terrain, with open channels, sections built against rock and small aqueducts where streams cross. The Ruet, a diminutive channel near Ville-sur-Sarre, includes a stone aqueduct over the Clusellaz stream and a wooden sluice gate, alongside later concrete and metal repairs.
Context and history
Mountain streams have long supplied water to the valley's agricultural land. The channels were maintained through shared rules governing water rights, cleaning and the distribution of flows. Their continued presence records the collective work that made cultivation possible on the slopes and valley floor.
