Cottbus (German pronunciation: [ˈkɔtbʊs]; Lower Sorbian: Chóśebuz; Czech: Chotěbuz; Polish: Chociebuż) is a university city in Brandenburg, Germany, situated around 125 km (78 mi) southeast of Berlin, on the River Spree. Cottbus is a major railway junction with extensive sidings/depots.
Cottbus is the cultural centre of the Lower Sorbian minority. Many signs in the town are bilingual, and there is a Lower Sorbian-medium Gymnasium, and Sorbian Quarter, but Sorbian is rarely spoken on the streets.
Next to Cottbus is the famous Branitz Park, created by Prince Hermann von Pückler-Muskau after 1845. Schloss Branitz (Branitz Castle) was rebuilt by Gottfried Semper in a late Baroque style between 1846 and 1852, and the gardens laid by Prince Hermann feature two pyramids. One of these, the Seepyramide, is in the middle of an artificial lake and serves as his mauseoleum.
