Great Wall of China

The Great Wall of China is the longest wall on the Real World, in the country China.

The Great Wall appeared in an episode of The Adventures of Super Mario Bros. 3, "7 Continents for 7 Koopas". When King Koopa tried to conquer the entire Real World, he put Bully Koopa under control of Asia. Bully vandalized the Great Wall of China by putting graffiti all over it. Mario later stole Bully's wand, and restored the Wall to its former glory.
