Administrative region of Zasavje is not considered as Spodnja Štajerska anymore (even less than Posavska), but it would be the right thing to mention it here. Especially because geographic area from west of Ljubljana Basin to the hills around the Sotla River is called Posavsko hribovje, recently also Vzhodno Predalpsko hribovje. The area contains almost 10% of the area of Slovenia, and it is more than 25 kilometers wide and 70 kilometers long.
Also Spodnja Štajerska is divided into several parts. At the upper part of the Savinja River, there is Zgornja Savinjska dolina valley with Logarska dolina, one of the most beautiful Alpine valleys, where the river Sava springs in the waterfall Rinka. Zadrečka dolina by the river Dreta is also considered a part of Zgornja Savinjska dolina. The highest mountains in this area are part of Kamnik-Savinja Alps (Planjava, Ojstrica), but also Oljševa with Potočka zijalka and Velika Raduha (2062 m) with Snežna jama are very famous. Two of the biggest settlements there are Solčava with gothic parish church of Saint
Styria is the largest Slovenian region. It is probably going to be divided into three parts ? new administrative regions. In that area, Styria is going to be divided into two parts, one at the Drava River ? Podravje or Gornja Štajerska (Upper Styria), and the other at the Savinja River ? Savinjska or Spodnja Štajerska (Lower Styria). Let?s take a look at Spodnja Štajerska for the beginning, also because we can reach Savinjska and then Gornja Štajerska over already mentioned passes Črnivec, Motnik, Trojane and Kanderše.
Under the authority of Austria, Notranjska was part of Carniola, which extended from Ljubljana Basin to Kras and Istria. Borders of Notranjska are not simple to define at all. The best way to do this is probably to follow the borders of former municipalities, today administrative units. Notranjska consisted of municipalities Vrhnika, Logatec, Postojna and Ilirska Bistrica, while Idrija has always been specialty in administrative and language respect. It has been considered as a part of Severna Primorska, Notranjska and even Ljubljana. Also the municipality Ilirska Bistrica wants to become a part of the new coastal province, instead of Notranjska.
Lower part of the former Carniola is now called Dolenjska; recently, it has been often named only as southeastern Slovenia. It extends from the Ljubljana Basin to the border with Croatia. It is separated from Styria with the river Sava on the north, from Croatia with the river Kolpa on the south and with the Bloke plateau on the west, where Notranjska begins. The southernmost part of Dolenjska with the largest city Črnomelj is called Bela Krajina. On the other side of the Kolpa River, Bela Krajina ends, as well as Slovenia.
