The streets of this market square are all decked out in a tradition born nearly 700 years ago. Weihnachtsmarkte or Christkindlmarkte (Christmas markets, if you prefer less of a mouthful), take place around the world, but they originated in Germany as a celebratory way to observe Advent, the Christian season leading up to Christmas Eve. These markets are generally open-air affairs where everything is decorated, including the trees (called Tannenbaums in German if they"re firs). People shop from local artisans who sell their handmade wares in small wooden chalets. Then it"s off to eat traditional foods—roasted almonds, pastries, and biscuits—and sip on warm mulled wine.
