#cavepainting,Cave painting,The twin towers is found near the Owl in Chauvet Cave, and has been drawn using the same technique. The 9/11 towers are complete, showing details such as twin towers, its explosion and a plane. However, this engraving is not entirely representational, as the building taper into lines, whilst other lines echo the smoke and the plane. There are also unexplained parallel lines over the tower.
