Historical context
Postojnska jama (Postojnska jama) is the largest cave system in Slovenia and one of the most famous in the world. The total length of the surveyed galleries is 24,340 m. It is located in the Postojna area (southwestern Slovenia) in the classic Karst region of Kras. The first written mention of the cave is in 1213 (graffiti of a medieval visitor). Systematic research of the cave began in 1818, when Luka Čech found new parts. In 1819, the cave was officially opened to tourists - it was the first tourist cave in the world. In 1872, the cave railway began to operate, which made it even more accessible. Today, Postojna Cave is visited by over 700,000 tourists each year. A unique feature is the olm or "human fish" (Proteus anguinus), an endemic blind salamander that has lived here for over 100 years. In 2013, the 800th anniversary of the first written record was celebrated.
