Description
Français : Version en français plus bas

From a geological point of view, the cave is several million years old. The first human traces discovered in the cave date back to the Pleistocene glaciation. The cave of Postojna is a karst network located near the town of Postojna in Slovenia about 50 km southwest of the capital Ljubljana. The cave of Postojna is a tangle of more than 20 km of caverns and galleries (discovered until today), where in 185 years passed more than 30 million visitors2. Indeed, these are the largest caves of the Carso, as well as the most visited of Europe. In the Pivka river complex, the most famous caves are the Cave of Postumia, the Otok Grotto, the Abisso della Pivka, the Black Cave and the Cavernone della Planina.


A view of the cave. The caverns are rich in stalagmites and stalactites which form imperceptibly, and whose formation requires thousands of years. The development of these stalagmites and stalactites is due to the influx of water containing calcium carbonate which deposits forming the concretions. The average temperature of the cave is 10 ° C, which increases slightly in summer and decreases somewhat in winter. On the other hand, the humidity is very high and it is advisable to dress a raincoat for visits.

D'un point de vue géologique, la grotte est vieille de plusieurs millions d'années. Les premières traces humaines découvertes dans la grotte remontent à la glaciation du Pléistocène .

La grotte de Postojna est un réseau karstique situé près de la ville de Postojna en Slovénie à environ 50 km au sud-ouest de la capitale Ljubljana. La grotte de Postojna est un enchevêtrement de plus de 20 km de cavernes et galeries (découvertes jusqu’à aujourd’hui), où en 185 années sont passés plus de 30 millions de visiteurs2. En effet, ce sont les plus grandes grottes du Carso, ainsi que les plus visitées d'Europe. Dans le complexe hydrographique de la rivière Pivka, les cavernes les plus célèbres sont la Grotte di Postumia, la Grotte de Otok, l'Abisso della Pivka, la grotte Noire et le Cavernone della Planina.

Une vue de la grotte. Les cavernes sont riches de stalagmites et stalactites qui se forment de façon imperceptible, et dont la formation demande des milliers d’années. Le développement de ces stalagmites et stalactites est dû à l’afflux d’eau contenant du carbonate de calcium qui se dépose formant les concrétions. La température moyenne de la grotte est de 10 °C, qui augmente légèrement l’été et diminue un peu l’hiver. Par contre, le taux d’humidité est très élevé et il est conseillé de se vêtir d’un imperméable pour les visites.
