Poggio Silvestre
The quarry of Poggio Silvestre is a source of top quality white marble classified since the last century and active since ancient times.
Emanuele Repetti, an academic of Georgofili, in the first volume of his “Physical historical gazetteer of Tuscany” of 1833 gives a detailed description (though erroneously quoting the name of the quarry as Poggio Silvestro): “At the opposite side [of the canal of Torano] the quarries of Poggio Silvestro can be seen, which can offer the bardiglio (saccharoidal cyan calcareous) of the Grotta de' Corvi, the beautiful statuary of Zampone, and those which bear the name of poggio Silvestro itself”.
