Ore Mountains (German: Erzgebirge; Czech: ), a low, wooded mountain range forming part of the German-Czech border. The range extends northeast-southwest, separating the German state of Saxony and the Czech region of Bohemia. Length is about 100 miles (160 km), width about 20 miles (32 km). KlĂ­novec, in the Czech Republic, is the highest peak; it rises to 4,081 feet (l,244 m) above sea level. There are no large cities in the mountains. Mining and lumbering have been leading occupations for centuries. Germans occupied virtually the entire area from medieval times until after World War II, when they were largely replaced in Bohemia by Czechs.
