The capital city of which European country lies on the River Ljubljanica?
Ljubljanica Ljubljanica The Ljubljanica (), known in the Middle Ages as the "Ljubija", is a river in the southern part of the Ljubljana Basin in Slovenia. The capital of Slovenia, Ljubljana, lies on the river. The Ljubljanica rises south of the town of Vrhnika and outflows in the Sava River about downstream from Ljubljana. Its largest affluent is the Mali Graben Canal. Including its source affluent the Little Ljubljanica (), the river is in length. The Little Ljubljanica joins the Big Ljubljanica () after and the river continues its course as the Ljubljanica. The Ljubljanica is the continuation of several karst
Ljubljanica rivers that flow from the Prezid Karst Field () to Vrhnika on the surface and underground in caves, and so the river is poetically said to have seven names (six name changes): Trbuhovica, Obrh, Stržen, Rak, Pivka, Unica, and Ljubljanica. The Ljubljanica has become a popular site for archaeologists and treasure hunters to dive for lost relics and artifacts. Locations in the river between Ljubljana and Vrhnika have offered up pieces of history from the Stone Age to the Renaissance, belonging to a variety of groups, from local ancient cultures to more well-known groups like the Romans and the Celts.
