Quote of The Day

You cannot stay on the summit forever; you have to come down again. So why bother in the first place? Just this: What is above knows what is below, but what is below does not know what is above. One climbs, one sees. One descends, one sees no longer, but one has seen. There is an art of conducting oneself in the lower regions by the memory of what one saw higher up. When one can no longer see, one can at least still know.

Europe, Slovenia, Postojna - Postojna cave

Postojna Cave is a 20,570 m long Karst cave system near Postojna, Slovenia. It is the longest cave system in the country. The caves were created by the Pivka River.

The cave was first described in the 17th century by Johann Weichard Valvasor, and a new area of the cave was discovered accidentally in 1818 by local Luka Čeč, when he was preparing the then known parts of the cave for a visit by Francis I, the first Emperor of Austria. In 1819, the caves were opened to the public, and Čeč went on to become the first official tourist guide for the caves. Electric lighting was added in 1884, preceding even Ljubljana, the capital of Carniola, the Austro-Hungarian province the cave was part of at the time, and further enhancing the cave system's popularity. In 1872 rails were laid in the cave along with first cave train for tourists. At first, these were pushed along by the guides themselves, later at the beginning of the 20th century a gas locomotive was introduced. After 1945, the gas locomotive was replaced by an electric one. 5.3 km of the caves are open to the public, the longest publicly accessible depth of any cave system in the world.

The caves are also home to the endemic olm, the largest trogloditic amphibian in the world. Part of the tour through the caves used to include a pool with some olms in it, though these have been removed recently due to the effect of flashes from visitngs tourists cameras had on the sensitive skin of the olms.
