Postojna Cave, Show cave in Postojna, Slovenia
The cave system stretches over 24 kilometers through limestone formations, featuring numerous passages filled with white stalactites and stalagmites shaped by water.
The first documented exploration occurred in 1818 when Luka Čeč discovered new sections while preparing for Emperor Francis I of Austria-Hungary's visit.
The underground railway system, installed in 1872, transformed the cave into a major European tourist destination and influenced the development of cave tourism.
The standard guided tour combines a 3.5-kilometer train journey through illuminated chambers with a 1.5-kilometer walking segment across designated paths.
The cave houses an underground post office established in 1899 and maintains a stable temperature of 10 degrees Celsius throughout the year.
