The fascinating walkable sculpture called Tiger and Turtle by Thomas Mayer is located in Duisburg, Wanheim and has been accessible by the public since the 13th November 2011. It is built on top of an artificially heaped plateau, which allows the walkers to rise more than 45m or 49 yards into the air and enjoy rather impressive views over the Rhine.
