I am beyond thrilled for the opening of the Chauvet Cave replica (which was built by 3D modeling!). Chauvet Cave itself has been long closed, due to the rapid deterioration of the rock art that came with increased human visits. Some lucky people however, get to experience the real deal. Here is one recollection of what it is like in there.
And if you haven’t seen the Werner Herzog Cave of Forgotten Dreams documentary, I very much suggest it. It has stunning imagery of the art inside, and some really great information and stories from researchers.
