The Glass Museum is the most important testimony of an ancient glass processing tradition that has characterized Piegaro and its economy since the 13th century. The building that currently hosts the exhibition is the last venue in the village walls of Vetreria which was dismantled in 1968, shifting production to a new plant in the valley of the country, still existing. The Museum inaugurated on April 18, 2009 preserves the old look of the Glassworks and houses many types of artifacts from the Chilean kilns. Of the ancient melting furnace remains the base of the perimeter wall which encloses part of the last glass in its interior when it was switched off in 1968, when a large amount of incandescent glass, still present in the melting basin, was poured into a room on the basement floor. Today, the large glass casting, with its intense emerald green, is undoubtedly the most evocative view within the museum path, an effective "monument" to the centuries of productive history that took place in the heart of the village of Piegaro.
