The Bavarian Forest is a region known for glass blowing, and Passau, the city of three rivers, was the centre of this trade for centuries; artisans sent their wares from here to the rest of the world. The Glasmuseum Passau glass museum is not only home to the largest collection of European glass in the world, but also offers an overview of over 400 years of the glass trade.
