At ItalianSide, we have a big collection of old photos from almost every town in Piemonte and in Italy (We have more than 90% of Italian towns in our pictures archives!).
We have several images of Briga Alta 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 Briga Alta and its area.

If you are interested in this or other pictures with no watermark of Briga Alta just send an email to brigaalta@italianside.com, with your request.
