Visitors travelling from Florence to Volterra, or to Monteriggioni and Sienna, via Poggibonsi often overlook Colle di Val d'Elsa because they pass only the modern part of the town. In fact, Colle di Val d'Elsa has a small but attractive old town with two important provincial museums, the Museum of Civic and Religious Art and the Archaeological Museum, as well as quite a good Museum of Lead-Crystal Glass.
