Upper Silesia, Historical region in southwestern Poland and northeastern Czech Republic.
Upper Silesia is a historical region in southwestern Poland and northeastern Czech Republic that covers rolling plains crossed by the Oder River. The landscape shows a mix of forests, fields, and densely built areas shaped by coal mining and heavy industry.
The region changed hands many times over centuries between Bohemian, Habsburg, and Prussian territories before being divided after World War I. New borders emerged through plebiscites and League of Nations decisions that split the area among Poland, Czechoslovakia, and Germany.
The population of Upper Silesia maintains distinct traditions, including the regional Silesian language, which contains elements of Polish, German, and Czech influences.
The region is accessible through several main transport routes, including international rail lines and highways that connect larger cities. Visitors will find information centers in Katowice, Opole, and Ostrava offering maps and guidance about local sites.
The region holds a collection of industrial monuments that have been transformed into museums and cultural spaces over recent decades. Former mining facilities and steelworks now host exhibitions about the industrial development of central Europe.
