Postojna is of course one of the most famous caves of the world. One reason is the good accessibility of the cave: the natural entrance on the hillside is rather big, the cave itself is really huge and horizontal. So people visited the cave for many years, left their names on the walls and blackened the formations with their torches. But on the other hand this country was inhabited for a long time, it's in the center of Europe, many people visited this country and also explored this "easy" cave. And several of those visitor wrote descriptions, Johann Weichard Frh. von Valvasor and others, and spread the word. At last there were numerous congenial cave administrators who developed the cave for tourism and made the cave well known all over the world.
The cave has a long history and was used for many purposes. It was used as storage room, as hideout, as bunker, and the Germans used it as an fuel depot during World War II. When the fuel was destroyed by partisans, the explosion and the fire, which burned for seven days, destroyed also a huge passage of the cave. The partisans were guided by a former cave guide and entered through Crna jama, and used the artificial tunnel dug by the Italians to enter Postojna from behind. The Italians took all cave maps with them when they left, so the Germans did not know about this rear entrance and did not guard it. Today this tunnel is used for an alternative cave tur which combines Postojna and Crna jama.
But the first part of the cave, several hundred meters, is black and dirty from visitors of the last centuries. And not only candles and torches are to blame. The visitors wrote their names on the walls, to tell anyone they were there. This behavior is today considered very impolite, a sort of vandalism. But several hundred years ago it was just common, no one had a thought about cave protection. And the former cave vandalism is today a reasearch area for historians, as several famous people left their names on the walls.
Today the visitors traverse this area very fast on the cave train, which takes them about 5 km into the cave, where the tours take place. And the cave is so big, it has several other human installations beneath the train: a cave restaurant, a concert hall for more than 10.000 people, and the cave post office.
The building at the entrance of Postojna Cave was built in the last century. This was the time, when the growth of science made the whole area famous all over Europe. At the fact that Slovenia belonged to the Donaumonarchie (Austro Hungarian Empire) allowed many people to travel freely to Postojna and visit the cave. That's a situation we do not quite have anymore, despite Schengen.
