Performers wearing traditional outfits demonstrate the Coopers' Dance on Marienplatz square on January 7, 2012 in Munich, Germany. The Coopers' Dance, known in German as the Schaefflertanz, is performed only every seven years and dates back to 1702. Though originally performed by young, unmarried coopers who built the beer barrels used by Munich breweries, participation has seen a steady decline as the number of working coopers has dwindled. This year seven of the performers are coopers. The dance is also represented in the dancing figures of the Munich City Hall carillon, one of the city's biggest tourist attractions.
