Streets and Sidewalks in the center of Central European Cities

While the streets are cobblestones in much of the old central cities, Prague has worked to make their sidewalks pretty using blocks set out like a mosaic. The problem is that many of the individual blocks are missing or loose. You have to watch your step. It is not a problem, I suppose, for the young, but note my cane at 3 o'clock in this photo. It was a little difficult for me. Worth it, but difficult.
