The landscape is marked by the monumental entrances of ancient slabs quarries of particular rocky levels of the Scaglia Rossa Veneta. Its peculiar characteristic is that of constantly presenting, in a section with a thickness of about 8 meters, 73 very regular layers of white-pinkish, modular marly limestones, already naturally separated from each other by a thin veil of clay that facilitates their detachment. This dense and regular stratification has thicknesses ranging from 3 to 20 centimeters and rare and isolated levels of 30-35 centimeters. The color of the rock is variable, with shades ranging from white, to gray and golden. In Valpolicella it has been quarried for centuries, even if at present the studies on the subject do not provide any insight into whether the spectacular Prun quarries could be of Roman, medieval or modern origin. Certainly small preare (stone quarries) existed in the area, as in all of Lessinia and in the Veronese hills, since prehistoric times. In fact, remains of prehistoric houses entirely in stone have been found, from the roofs, to the side walls, to the pavements.
