Natural Monument of Camposoriano

where beauty becomes extraordinarily natural

Campo Soriano is a natural area in the municipalities of Terracina and Sonnino, included in the Monti Ausoni and Lago di Fondi Regional Natural Park.

The protected area extends for 974 hectares in a vast karst basin of the Ausoni mountains between Monte Romano and Monte Cavallo Bianco, of great geological and landscape interest. In addition to its extraordinary beauty, this landscape represents one of the most important karst plateaus in Italy.


The valley is defined with a term of the Serbian language: polje . Here you can recognize the stages of the evolution of the karst basin (fault, glacial modeling, gelivation, lake phase, emptying). The karst polje is a vast collapse sinkhole formed by erosion and corrosion over a very long time.


It is bordered by an uninterrupted rocky edge that can even reach a certain height. The bottom is flat, of the typical red color, and very fertile in all its extension: it is not for nothing that the cultivation of the rare Moscato di Terracina grape is widely practiced, whose production is promoted by a festival in La Fiora.


Among the phenomena observable in the poljie are:

  • the sinkholes, of circular hollows

  • the sinkholes, real deep and narrow cavities

  • the natural cisterns, very important water reserves for the inhabitants of the place

  • the hum, the remains of rock formations shaped for millennia by atmospheric phenomena


Among the geological elements peculiarities of Campo Soriano, the hum stand out, isolated rocky struts that emerge from the ground in the shape of spiers reaching the maximum height in the Rava di San Domenico, also known as the Cathedral, of 18 meters.


The hums seem to all intents and purposes like stacks of earth that abruptly break into the landscape with a scenic effect that does not leave indifferent.

Among the hums of Capo Soriano, the most important is the one known as La Cattedrale, an imposing boulder about 18 meters high, with a shape reminiscent of a Gothic cathedral.

For the locals, the cathedral is linked to the Benedictine monk San Domenico da Sora, a very revered saint in southern Lazio, for this reason they call it Rava di San Domenico.
This monolith stands out right in the center of the valley, like a silent guardian, and thanks to its fame it has become the symbol of the Park.


Some remains of ancient bricks, which close a natural niche, also indicate the location of a votive image. The dedication of the Rava to San Domenico was given by a Benedictine monk. Technically, the Cathedral is a residual limestone relief that stands at the bottom of a karst plane.
