N2...I don't believe that Lascaux or Altamira Caves are open to the Public anymore...they were both ravaged by Fungus's brought in due to Tourism...and the Paintings started to crumble and die...I believe that They both made virtual Tours...and some have been recreated for Tourists...it would be a shame for all of these to just rot from Fungus because We wanted to wander through them like Carlsbad Caverns in New Mexico...I hope that one day they find a way for the Public to be able to see them without doing more damage...great history for sure....thanks Grunt for reminding Me of this treasure!
