The biggest amount of ancient painting was found in Europe (from Spain to Ural). It is preserved in a good condition on the walls of caves, which entrances were blocked thousands years ago. During the years the same temperature and humidity were preserved there naturally. That is why not only wall painting, but also footsteps of grown ups and children on the wet floor could be seen.
