I like this quiz! Simple, and easy for those who know it! Perhaps another quiz that's basically the inverse of this? (Example: The Great Pyramids of _____)
So. A guy decided to write down wonders of his known world. He gets to 6 and instead of stopping there or choosing some other existing structure, he decided to make one up just to have 7. Yeah, right. Just some "scientist" trying to get recognised.
Also the Colossus of Rhodes may have never existed, accounts of it are inconsistent (some say it overmatched the docks with boats passing underneath it, which would have it of huge size and would be in conflict with further tales of the Colossus falling into the sea with boats passing above it, etc.)
Maybe an idea, would be to split the name of the city and the monument. So we would have 14 answers. 1 for Hanging Gardens and another answer for Babylon.
