The Euganei Hills as well as for the production of wine are famous also for the extraction of trachite.It has been used in the era paleoveneta for the construction of building works and building works in the Roman epoch water channels. In the fifties was used to rebuild the banks of the Po after the flooding mainly in the province of Rovigo.This caused an abuse in financial terms as the trachyte was sold only on paper without the state control in the quantities extracted, resulting in an enrichment of the quarrymen. It is a hard stone, igneous, silica, with various colors. Brown with darker veins, blue-gray, gray, blue-brown, yellow-brown. Many palaces, squares, art of Padua, Venice, Vicenza, Treviso and not only worked with this stone. It is a rock that lends itself to any type of processing, from the works in "facing" and bocciardati, to those smoothed and polished. It is often turn to wood saw his likeness. In ancient times it was stated that the trachite was a living stone cutting as a rock just unplugged from the wall on the inside you can see a trickle of water. The stonecutters who worked the trachyte of the Colli di Padova were also natives. The quarries that have for centuries donated riches to our Venetian works of art are now bound and can no longer give continuity to the prestige of constructions and restorations with this stone impoverishing the area despite resources of advanced ecological upgrading.
