historical costumes, Salzburg
Watch out for the parades - especially on sundays and special festivities like Easter-Sunday, when I took this picture.

Yes, people dress up to drink beer! Don't be afraid to investigate any events going on while you are visiting. I stumbled on this huge tent set up near the Dom, and there was my oompah band and locals in period dress serving and drinking Stiegl-Bier (the local beer of Salzburg) as well as a lot of people enjoying themselves on a lovely afternoon in Salzburg! What a pleasant surprise! Look for many of these! You can see the top of this tent in my first picture on this page, with the vista of Salzburg.
