Take Arts et Métiers, for example. It's a busy traffic junction, and pretty plain (apart from the wonderful inventions museum that has to be seen to be believed). However, if you look up at one corner, you'll get a surprise.

Usually hidden by the trees, the side of one building is adorned by a giant angel! Most people don't even know that it's there. Can't say I know much about it, but it's another little detail that make Paris a beautiful and surprising city. If you're in the area, see if you can spot it! (P.S. There's a map after the photos to help you out).

Arts et Métiers, Paris 3rd arrondissement, métro - erm... - Arts et Métiers (lines 3 & 11)
