Got to be these lovely old gas lamps I saw in Kaiserswerth near Düsseldorf a few years ago. Sorry it's not the best shot, but I was just taking a general photo of the area, I wasn't aiming specifically at the lamps.

I’ve never been to Europe, so haven’t seen any firsthand, but I did like the simple design of the ‘pot’, a lantern used in Germany, and posted by Kai back in 2010 see here https://www.lighting-gallery.net/gallery/displayimage.php?pos=-43421

Since I live rather close to France I do very like French street lights. I like the old ones which are very simple built but also some more modern ones which were well designed.
