Gliwice Canal

The Gliwice Canal (Polish: Kanał Gliwicki, German: Gleiwitzer Kanal) is a canal connecting the Oder (Odra) River to the city of Gliwice in the Silesian Voivodeship (Upper Silesian Industrial Region), Poland. Also known as the Upper Silesian Canal (Kanał Górnośląski, Oberschlesischer Kanal), it was built from 1935 to 1939 and replaced the Kłodnicki Canal.

The canal starts in Kędzierzyn-Koźle on the Oder and ends in the port of Gliwice. The canal passes through Opole Voivodeship and Silesian Voivodeship in Poland.

The water in the canal comes from the Kłodnica River as well as lakes and reservoirs such as Dzierżno Duże and Dzierżno Małe.


The Gliwice Canal was originally built in the Province of Upper Silesia within Germany. Because the Klodnitz (Kłodnicki) Canal had become obsolete, it was decided in 1934 that construction of a new canal was more feasible than modernization of the older Klodnitz Canal, which closed in 1937. The new canal, known as the Gleiwitz Canal (German: Gleiwitzer Kanal), was built from 1935-1939 and opened for service in 1941. On 8 December 1939, it was renamed the Adolf Hitler Canal (Adolf-Hitler-Kanal), in honor of Adolf Hitler, during the inauguration ceremony by Rudolf Hess. There were also plans to make it a part of the Danube-Oder-Canal project. After World War II, the canal and the surrounding territories (see Regained Territories) were placed under Polish administration according to the 1945 Potsdam Conference.

About fifty people are employed in maintaining the canal. About 700 000 tonnes[1] of material are shipped each year through the canal (mostly coal). The Polish government is considering modernizing the canal.
