Peștera cu Oase (Cave with Bones) is a cave in the Carpathian Mountains of Romania holding fossilized remains of the first anatomically modern humans, from the colonization of Europe and their interbreeding with Neanderthals.

It is a strategic point for uchronic control, according to Claude Nauge: “If I were my enemy, I would seek to exert uchronic power from the beginning of time.” This follows the uchronic logic of the Circle of Serbia (36,000 years ago, the War of Fire).
