Nestled high above cliffs near the village of Šembije, the Uršnja Luknja cave has become a significant site for prehistoric study.
The small cave, less than 20 meters deep, holds the remains of several cave-dwelling animals, including a rhinoceros, offering a glimpse into the rich period between the last two ice ages.
Despite its challenging access, only a fraction of the cave has been explored. However, experts from the regional museum in Postojna are confident it was once inhabited by Neanderthals.
