Inner Carniola (Slovene: Notranjska pronounced [ˈnòːtɾanska]; German: Innerkrain) is a traditional region of Slovenia, the southwestern part of the larger Carniola region. It comprises the Hrušica karst plateau up to Postojna Gate, bordering the Slovenian Littoral (the Gorizia region) in the west. Its administrative and economic center of the region is Postojna, and other minor centers include Vrhnika, Logatec, Cerknica, Pivka, and Ilirska Bistrica.

Emona (early Medieval Greek: Ἤμονα) or Aemona (short for Colonia Iulia Aemona) was a Roman castrum, located in the area where the navigable Nauportus River came closest to Castle Hill, serving the trade between the city's settlers – colonists from the northern part of Roman Italy – and the rest of the empire. Emona was the region's easternmost city, although it was assumed formerly that it was part of the Pannonia or Illyricum, but archaeological findings from 2008 proved otherwise.

The Visigoths camped by Emona in the winter of 408/9, the Huns attacked it during their campaign of 452, the Langobards passed through on their way to Italy in 568, and then came incursions by the Avars and Slavs. The ancient cemetery in Dravlje indicates that the original inhabitants and invaders were able to live peacefully side by side for several decades. After the first half of the 6th century, there was no life left in Emona. The 18th-century Ljubljana Renaissance elite shared the interest in Antiquity with the rest of Europe, attributing the founding of Ljubljana to the mythical Jason and the Argonauts. Other ancient Roman towns located in present-day Slovenia include Nauportus (now Vrhnika), Celeia (now Celje), Neviodunum (now the village of Drnovo) and Poetovio (now Ptuj).

The Rovte dialect group (rovtarska narečna skupina, rovtarščina) is a group of closely related dialects of Slovene. The Rovte dialects are spoken in the mountainous areas of west-central Slovenia, on the border between the Slovenian Littoral, Upper Carniola, and Inner Carniola, in a triangle between the towns of Tolmin, Škofja Loka, and Vrhnika.

The Municipality of Vrhnika (pronounced [ˈʋəɾxnika] ; Slovene: Občina Vrhnika) is a municipality in Slovenia. The administrative seat of the municipality is the town of Vrhnika.

The Ljubljanica (pronounced [ljuˈbljáːnitsa]), known in the Middle Ages as the Leybach, 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 flows into the Sava River about 10 kilometres (6.2 mi) downstream from Ljubljana. Its largest affluent is the Mali Graben Canal. Including its source affluent the Little Ljubljanica (Slovene: Mala Ljubljanica), the river is 41 km (25 mi) in length. The Little Ljubljanica joins the Big Ljubljanica (Slovene: Velika Ljubljanica) after 1,300 m (4,300 ft) and the river continues its course as the Ljubljanica.

The Ljubljanica is the continuation of several karst rivers that flow from the Prezid Karst Field (Slovene: Prezidsko polje) 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.
