Trnje (pronounced [ˈtəɾnjɛ]) is a village east of Pivka in the Inner Carniola region of Slovenia.
Trnje is the site of two known mass graves associated with the Second World War. The Tiček Cave Mass Grave (Slovene: Grobišče Tičkova jama) lies north of the village, in a shallow karst valley on the east side of Lake Petelinje (Petelinjsko jezero). It contains the remains of undetermined victims based on human bones found at the site by spelunkers. The Shaft 1 by the Muha Enclosure Mass Grave (Grobišče Brezno 1 pri Muhovi ogradi) lies 2 km northeast of the village. It was excavated in October 2009, revealing 37 victims and eight German military ID tags. The remains were reburied in December 2009 in Block F of the German military cemetery in Celje.
The parish church in the settlement is dedicated to the Holy Trinity and belongs to the Koper Diocese. It was built in 1895 in the neo-Romanesque style based on plans by the architect Raimund Jeblinger. It stands on a small hill south of the village.
Pivka is a small town in Slovenia in the Pivka Basin in the Karst region. It is the seat of the Municipality of Pivka. It belongs to the traditional region of Inner Carniola.
Pivka was first mentioned in 1300 as villa Sancti Petri super Piucha ('St. Peter above the Pivka River'), and in 1498 as Sannt Peter. The name of the settlement was changed from Šent Peter na Krasu (literally, 'Saint Peter in the Karst') to Pivka in 1952. The name was changed on the basis of the 1948 Law on Names of Settlements and Designations of Squares, Streets, and Buildings as part of efforts by Slovenia's postwar communist government to remove religious elements from toponyms. Before it replaced the original name of the settlement, the name Pivka originally referred to the Pivka River. This name was first attested in 1300 as Piuca or Piucha (and as Peucha in 1335). The name is derived from the Slovene common noun pivka 'karst sinkhole'.
Although the Pivka region has been a strategically important location since ancient times, it became even more important with the construction of the railway from Vienna to Trieste (the Austrian Southern Railway) in 1857 and the railway from Št. Peter na Krasu to Rijeka twenty years later. In 1930, while it was under the Italian control, the strategic hills over the town were heavily fortified and included in the Alpine Wall system of defenses, which stretched from the Bay of Genoa to the Kvarner Gulf. Št. Peter na Krasu and the nearby barracks in Hrastje (now part of the town of Pivka) were one of the strongest points in the eastern section of the Alpine Wall.

The Pivka is a karst lost river in Slovenia. The river is 27 kilometres (17 mi) in length. The Pivka ends in Planina Cave, where it merges with the Rak River and then the Unica River. The confluence of the Pivka and the Rak is one of the largest subterranean confluence in Europe. The Pivka created Postojna Cave, the longest cave system in Slovenia as well as one of its top tourism sites.
