The riverWarta (/ˈvɑːrtə/VAR-tə,Polish:[ˈvarta]ⓘ;German:Warthe[ˈvaʁtə]ⓘ;Latin:Varta) rises in centralPoland and meanders greatly through the Polish Plain in a north-westerly direction toflow into theOder atKostrzyn nad Odrą on Poland's border withGermany. About 808.2 kilometres (502.2 mi) long, it is the second-longest river within the borders of Poland (after theVistula), and the third-longest Polish river after the Oder (which also flows through theCzech Republic and Germany).[1] Itsdrainage basin covers 54,529 square kilometers (21,054 sq mi).[1] The Warta is navigable from Kostrzyn nad Odrą toKonin - approximately half of its length.[2]
The Warta connects to the Vistula via its own tributary, theNoteć, and theBydgoszcz Canal (Polish:Kanał Bydgoski) near the city ofBydgoszcz.
The Greater Warta Basin defines the site of early Poland; it is said that the tribe ofWestern Polans (Polish:Polanie) settled the Warta Basin between the 6th and 8th centuries. The river is also mentioned in the second stanza of the Polish national anthem, "Poland Is Not Yet Lost".
