Sacco, River in Lazio, Italy.
The Sacco is a river in the Lazio region of central Italy, rising in the Monti Simbruini mountains and flowing southeast through the Ciociaria area. It runs between the provinces of Rome and Frosinone before eventually joining the Liri River.
The ancient Romans called this river the Tolerus and relied on it to supply settlements across the interior of Lazio. Over the centuries it remained a constant feature of the landscape between the Apennines and the Liri valley.
The river shapes daily life for communities along its course, serving as a natural dividing line between settlements. Locals have adapted their lives to its presence over generations, using its banks as part of their landscape.
The river can be reached from several towns along its course, and the banks are walkable in many spots. Visiting during drier months tends to give easier access to the water's edge and a clearer view of the riverbed.
Just before emptying into the Liri at Isoletta di Arce, the river receives two tributaries, the Cosa and the Alabro, in quick succession. This stretch of the lower course carries more water than any other section and gives the river its widest look.
