Treja Valley Park
Treja, an almost unknown river, a tributary of the Tiber. A shady and green landscape, where the waters have dug deep and branched gorges in the volcanic tuffs. Widespread but discrete animal presences, often denounced by signs picked by those who can interpret them: the acorns of the hedgehog, the imprint of the boar, the acute and interrogative call of the buzzard. And then the countries of Calcata and Mazzano Romano, expected microcosms to look out on tiptoe. A singular protected area, in the varied landscape of the parks of Lazio. The Treja is a modest watercourse that rises from the Sabatini mountains to merge into the Tiber at the height of Civita Castellana. There are about 30 km of route in which it crosses a largely cultivated countryside, but the waters over time have created a world still wild: it is that of the gorges, dug into the soft tuff of the ancient Sabatino volcano.
The protected area, established with L.R. September 22, 1982, covers 628 hectares in the territory of the municipalities of Calcata and Mazzano Romano. And 'that of the woods the most intense environment, a green ribbon that follows the stream meanders in the surrounding countryside. The borders of the park are longer than they have ever been. Here flow into the Treja River two streams, the ditch of the Mola and the Fosso della Selva, which flow between the vertical walls. The historical centers of Calcata and Mazzano Romano are the first historical-artistic emergencies of the park, there are many archaeological testimonies including those related to the ancient settlement of Narce.
In the southern sector of the Valle del Treja park you reach one of the most famous and appreciated areas of the protected area. With a modest height jump, the river water overcomes some differences in the rocks of the volcanic bed, here tuffs of particular resistance generated by a small eruptive center located very probably nearby and belonging to the ancient Sabatino volcanic apparatus. The Treja collects the rainwater of an area of about 490 km², eighty times more extensive than the park.
