Which river runs through the 2006 host city of Turin?

The Po River is the longest river in Italy and flows through the city of Turin, which hosted the Winter Olympics in 2006. This river is significant both geographically and culturally, as it runs from the western Alps to the Adriatic Sea, covering several important regions of Northern Italy. Turin, located in the Piedmont region, benefits from the Po River as it provides water resources and has historically been integral to the city's development and economy. The presence of the Po River is a defining characteristic of the landscape and contributes to the overall identity of Turin. In contrast, the other rivers listed do not flow through Turin; the Arno runs through Florence, the Tiber flows through Rome, and the Adige runs mostly in the northeastern region of Italy.
