Thanks to its historical and natural habitat, the valley of Cagnemora is one of a kind. The Valle has recently returned some extraordinary archaeological testimonies that attest the rich context in which the area was placed. The first interesting core is a spring known as Fontana della Salce, a structure made up
of eight basins, one bigger than the other, that were probably used for the decantation of clays.
The second nucleus is currently under study and consists in what may be a site for leather  anufacturing and tanning and a great dovecot for the production of guano.
An extraordinary, refined Etruscan tomb is located near the site. The structure is entirely carved in stone and boasts a typical fake door, a coffered ceiling, and a funerary bad. This is one of the few peperino graves dating from the Etruscan era.
Downhill, a glacial erratic is characterized by carved tubs.
Higher up, the Piana degli Altari boasts examples of sepulchral altars transformed into shelters for animals. The several refuges and terraces that populate the area testify to the vitality that had characterized the valley until the last century.
