Serizzo of Formazza Quarry

The origin:

Valley of Ossola

The Ossola Valley is a vast alpine valley located north of Piedmont and bordering Switzerland, comprising several valleys including Formazza and Antigorio..
In these valleys, for millennia, the skill in extraction and the art of processing Serizzo have been passed down through generations.
The term “Serizzo” originates from ancient dialectal words used in the southern Alps, particularly in the regions of Piedmont and Ticino.
Therefore, it should not be understood as a precise petrographic definition; at times, it is used as an equivalent of “granite,” “gneiss,” or “gneissoid,” all rocks with a more or less metamorphosed granitic composition.
