Divje Babe is the oldest known archaeological site in Slovenia. The location of the site is a horizontal cave, long and up to wide; it is above the Idrijca River, near Cerkno, and is accessible to visitors. Researchers of Pleistocene climate change working at the site have uncovered more than 600 archaeological items in at least ten levels, including twenty hearths and the skeletal remains of cave bears. According to the museum's statements, the presumed flute has been associated with the "end of the middle Pleistocene" and with Neanderthals, about 55,000 years ago.
