Idrija is a small town and municipality with the same name in Slovenia. It is known for its mercury mine (today in the process of closing) and laces.
Near Idrija there was notable archeological find of 50,000 year-old flute, made of juvenile cave bear femur at Divje Babe.
According to legend, a bucket maker working in a local spring spotted a small amount of liquid mercury over 500 years ago. Idrija is one of the few places in the world where mercury occurs in both its elemental liquid state and as cinnabar (mercury sulfide) ore. The subterranean shaft mine entrance known as Anthony's Shaft (Antonijev rov) is used today for tours of the upper levels, complete with life-sized vignettes of workers over the ages. The lower levels, which reach to almost 400 meters below the surface and are no longer being actively mined, are currently being remediated.
