A layer of haze over the Taunus hills just north of Frankfurt is sharply separated from the sky above, Dec.3.

A roundabout turns on the little Christmas market in the old town of Frankfurt’s western Hoechst district, Nov.30.

Frankfurt’s traditional Christmas market opened this week. It was first mentioned in 1393 and is considered one of the most beautiful Christmas markets in Germany. It runs until December 22, 2013. (This photo was actually taken two years ago, but it basically looks the same every year.)
