Paving with natural stone

Since long, long ago man has considered important to pave roads and buildings with natural stone, just think to all the medieval (or even more ancient) castles and strongholds that still today exist on our territory.
These time and weather resistant structures alays get more and more attractive because they retain the “hisctorical” charm of natural stone. So paving with natural stone becomes nowadays a guarantee for architechts and engineer, who are promoting it instead of fake stone, consisting of concrete congregates or short-lived resins, devoid of every historical value.
