The Postojna that for two centuries have attracted millions of visitors from around the world, owe their fame to the masses of limestone formed from calcium deposits. These structures, called the stagmiti and stalactites of Postojna, grow unnoticed over hundreds of thousands of years. The development of different forms by the influx of water and limestone depends on the content of calcium carbonate in the water. The colors of the deposits of calcite (calcium carbonate) range from pure white to reddish brown or gray, according to the amount of dissolved substances in water droplets.
The Postojna (Postojna), are in the middle of the Karst region and Karst and its qualities are the source of the phenomena of rivers that cut into the rock their paths. The Postojna include 20 kilometers of caves known to date, including the most famous are the Postojna Cave, the Cave of Otok, the Pivka, the Black Cave and the Cave of Planina. The dry sections are for the most part open to tourists, while access to that water is suitable only for experienced cavers.
Access to Postojna Cave was known for centuries, but the inhabitants of Postojna presented a new opportunity to show tourists the riches underground in 1818, when a local resident, during the preparations for the visit of Austrian Emperor Francis I, he found parts of the caves completely unknown until then. The following year, the Postojna Caves were ready to receive tourist visits. The unusual shapes, and beautiful decoration created by the calcareous concretions attracted new visitors to the underground where it descended in the company of guides in the light of candles and torches.
the interest for the citizens of Postojna caves thought to facilitate the transport of the visitors with a cart pushed by hand from the guides on the rails and install the first plant of light electric current. In the last century, the train was pulling the hands of a locomotive engine with gasoline and this was some decades later, replaced by an electric locomotive.
