Bosna

: "This article is about the River Bosna. For the region see Bosnia (region), for other uses of the term Bosna / Bosnia, see Bosnia (disambiguation)."The Bosna (Cyrillic: Босна) is the third longest river in Bosnia and Herzegovina, and is considered one of the country's three major internal rivers, along with the Neretva and Vrbas Rivers; the other three major rivers of Bosnia and Herzegovina are the Una River, to the northwest, the Sava River, to the north, and the Drina River, to the east. The Bosna River flows for 271 kilometers (168 miles). Its name does not have any foreign variations. In the Roman times the river was called the "Bosona", and it is thought that this is probably the Illyrian origin of the name "Bosna".

Course and tributaries

The Bosna river also makes up the Bosna River Valley, the country's industrial center and home to close to a million people, as well as the location of several major cities. The river's biggest tributaries are the Željeznica, Miljacka, Fojnica, Lašva, Gostović, Krivaja, Usora, and Spreča rivers.

Its source is at the spring Vrelo Bosne, at the foothills of the Mount Igman, on the outskirts of Sarajevo, capital of sovereign Bosnia and Herzegovina. The spring is one of Bosnia and Herzegovina's chief natural landmarks and tourist attractions. From there, the Bosna flows northwards, through the heart of Bosnia, eventually becoming a right tributary of the Sava River in Bosanski Šamac.

Although it does not pass through any foreign countries, the Bosna flows through a number of cantons and regions of Bosnia. From its starting point in the Sarajevo Canton, it also flows through Zenica-Doboj Canton, Doboj Region, and Posavina Canton, in that order.

On its way north the River Bosna also passes through the cities of Visoko, Zenica, Doboj, Modriča and Bosanski Šamac.
