Visitors to Florence will no doubt walk along and cross over the river that runs through the city center; and while it’s possible to see the city these days without paying much attention to the river, that wasn’t always the case. The Arno River was once an incredibly important river to central Italy, serving as a “highway” that brought shipments from the sea and brought warring soldiers from neighboring cities. Today, the River Arno may not be as critical an avenue for shipping or armies, but it’s no less important to the identity of Tuscany.
The Arno River runs through Florence, as well as the cities of Pisa, Empoli, and Arezzo. Florence’s famous Ponte Vecchio (“Old Bridge”) spans the Arno, and hotel rooms with a river view usually command high prices. Also note that the part of central Florence located on the opposite side of the river from the Duomo and train station is known as the “Oltrarno,” or “other Arno,” meaning the other side of the Arno River.
The Arno isn’t always peaceful and romantic, however, as the river has flooded on several occasions, most notably in 1966 when 40 people died and many of Florence’s priceless art was damaged or destroyed. Today, you can still see flood markers on many buildings - but you’ll need to look up, as the water reached roughly 22 feet (6.7 meters) in the city center.
