Besides providing an excellent place to stay out of the rain, Arts et Metiers had enough incredibly well crafted, and often surprisingly beautiful quotidian objects, to keep us fascinated through many days of bad weather. Only the photos can give you an idea of the variety of displays covering the time from before 1750 to after 1950.

But why should that just be for robots?
