Every year, as Advent arrives and people's thoughts turn to the joy of Christmas, Europe repeats a tradition that is more than 500 years old. In countries from Sweden to Spain and in cities from Paris to Prague, Christmas markets are set up in town squares. The markets have become a commingling of commerce and community, selling holiday ornaments and gifts, as well as food and the omnipresent gluhwein, a hot, spiced red wine that cheers shoppers on a cold night. George Bauer takes viewers to several Christmas markets, beginning in Vienna and Salzburg in Austria, then going on to towns including Passau, Regensburg and Nurnberg.
