Zwiesel is a city in the Lower Bavarian district of Regen and since 1972 recognized spa resort. The town's name was derived from the Bavarian zwisl root word denoting the shape of a fork. The bifurcation of the rivers Big and Small rain rain and the intervening country was called Zwiesel. The town in the Bavarian Forest is known for the glass industry (Zwiesel crystal glass AG), crystal manufacturers (Theresienthal) and the glass school. Zwiesel called for this reason "the glass city". There are numerous other glassmaking and glass processing plants in the town. The motto of the city is "fine glass, fine wood are Zwiesel pride".
