Rive Rosse

Highlight • Natural Monument

The Rive Rosse are located in the eastern part of the Biellese.
The unusual landscape, from the Strona di Vallemosso Valley and through Masserano to Curino, is due to two of its geological peculiarities. Part of it is made up of hundreds of millions of years old granite formed in the subsoil of an old Paleo-African continent that was at the height of the Equator and which was "pushed" towards present-day Europe.
The other part is made up of huge lava flows that have completely covered the territory that would have become a part of eastern Biella after being submerged by primordial oceans and later "exhumed" during the uplift of the Alps about forty million years ago. .
These rocks have an orange-reddish color: and are called "Rive Rosse". If we also add up the strong erosion, which has been going on for several hundreds of thousands of years and which has transformed many slopes into deposits of large quantities of sand (there is even a church dedicated to the Madonna del Sabbione), it is understandable why the landscape takes on different aspects so unreal almost ... Martians!
