The Glass Museum is the most important testimony of an age-old glass processing tradition, which has characterized Piegaro and its economy since the 13th century. The building that currently houses the exhibition is the last seat, within the walls, of the glass factory that was moved in 1968.

The Museum preserves the ancient aspect of the glass factory and houses many types of artifacts from the kilns of Piegaro. Of the ancient smelting furnace the base of the perimeter wall remains. Today this large glass casting is without doubt the most evocative inspiration inside the museum.
