Kopačnica (in Slovenian pronounced as /kɔˈpaːtʃnitsa/, German: Kapatschnitz[2]) is a dispersed settlement in a small valley northwest of Gorenja Vas in the Municipality of Gorenja Vas–Poljane in the Upper Carniola region of Slovenia.[3]
Kopačnica consists of scattered farms along the valley of Kopačnica Creek and its tributaries: Podplečica Creek to the northwest, which flows through a canyon in the hamlet of Jezbirc, as well as Podkovščica Creek and Pohovica Creek in the Komajs Gorge (Slovenian: Komajska grapa) to the west, below Stara Oselica. The road to Cerkno passes through the Podplečica Valley, and a road to Leskovica through the Kopačnica Valley to the northeast. Surrounding elevations include Makovc Hill (920disp=orNaNdisp=or) to the east, Mah Hill (856disp=orNaNdisp=or) to the north, Mount Ermanovec (1026disp=orNaNdisp=or) to the south, and Vrhovec Hill (Slovenian: Vrhovčev grič; 1048disp=orNaNdisp=or) to the southwest. The village has hayfields and forested land, and some tilled fields in the lower area where the valleys join.[4]
The name Kopačnica is believed to derive from the verb kopati 'to dig' and may be related to the noun kopačina 'field cultivated by digging'.[5] In the past the village was known as Kapatschnitz in German.[2]
The Rapallo border between Yugoslavia and Italy passed through the area and the remnants of border guard posts are found nearby. During the Second World War, the Partisans maintained a checkpoint at house number 10 in the village.[4]
