Casamari Abbey

Highlight • Religious Site

One of the most stylistically significant abbeys in Italy and therefore certainly worth visiting is the Casamari Abbey, located in the far eastern territory of the municipality of Veroli, along the Via Mària, halfway between Frosinone and Sora. It stands out, imposing and solitary, close to a rocky hill bordered by the Amaseno stream, which in ancient times marked the border between the Ernici and the Volsci, at 300 meters above sea level. It was built on the ruins of the ancient Roman municipality of Cereatae Marianae (of which the aqueduct that served it is still visible), so named in honor of the goddess Ceres, to whom the place was consecrated, and of the valiant Roman general, Caius Marius, who he was born here and spent the first years of his youth.

Grande Waterfall of Isola del Liri

Highlight • Waterfall

Isola del Liri, with its waterfalls in the city center, is on the path of San Benedetto

The Acropolis of Arpino is an archaeological site close to the town of Arpino, one of the most important for the knowledge of the megalithic architecture of southern Lazio, not only for the large extension of the walls but also for their age, greater than that of other sites (according to some, it can be placed in the middle of the Iron Age, 8th/7th century BC), and classifiable according to the scale created by Giuseppe Lugli in the second way. The civitas vetus of the city, a typical example of Volsca fortification, represents one of the best preserved city walls built in polygonal work in pre-Roman times. It was probably the original nucleus of the primitive Volsco settlement (people of the 7th-6th century BC). Of particular significance is the presence of a "pointed arch", the only one of its kind that has survived in the entire Mediterranean area. This is a typical corbel arch, which constitutes a so-called scea door.
