One of the greatest man-made creations on the planet, the Great Wall of China has been immortalized both physically and with its incarnation as this 34'' x 46.5'' puzzle.  This gorgeous puzzle features one of the straighter stretches of the Great Wall curving up a mountain and running along lush green trees with the stunning blue sky in the background.

This gargantuan 4000 piece puzzle rivals the size of the Great Wall itself and is definitely an amazing feat to showcase once fully assembled.  A true pillar of any puzzler's collection.
