Ceppo di Gré is a sedimentary rock extracted in the province of Bergamo, on the North-western shore of Lake dIseo, fully respecting the environment. It was part of the architectural tradition of Lombardy since the Roman era and its use as a construction or decorative stone has always been significant due to its weather resistance and durability qualities. Easily matched with other materials due to its elegant charm, it is also appreciated in local and international modern architecture. It is especially indicated for outdoor use, for both facing and flooring.
