Postojna is a town and a municipality 35 kilometers from Trieste, in southwestern Slovenia. The area is known to have been populated since the Paleolithic era due to the finding of a cave settlement near the town of Postojna, called "Betalov spodmol". One of Slovenia's major tourist attractions is the Postojna Cave that is a home to the endemic animal olm, the largest troglodytic amphibian in the world. The cave was first described in the 17th century by Janez Vajkard Valvasor. Very close to Postojna is Predjama Castle built in 16th century in the mouth of another Karst cave.
