I have had the great good luck of having visited Switzerland more than 20 times, and am somewhat besotted with the architecture of the cantons that I know well, foremost being the Engadine area in the far eastern canton of Gräubunden. There, you see farmhouses a few hundred years old clustered in a hamlet, perhaps centered on a fountain from which livestock and their humans get good spring water. Many houses have decorated façades, the designs and illustrations - whimsical, familial, biblical, pagan - scraped into the wet, freshly whitewashed exterior walls, and often enhanced with color.
I found this today - no room for "sgrafitto" façade decoration here . . . It's all glass!
