At ItalianSide, we have a big collection of old photos from almost every town in Toscana and in Italy (We have more than 90% of Italian towns in our pictures archives!).
We have several images of Colle di Val d’Elsa too and here you can see one of them (click on the picture to enlarge).
If you are interested in historical maps, here you can see an old map (1800) of Colle di Val d’Elsa and its area.
If you are interested in this or other pictures with no watermark of Colle di Val d’Elsa just send an email to colledivaldelsa@italianside.com, with your request.
My paternal Grandfather is from this town. I’d love to see some photos. Who knows, he might even be in one or some of them.
