Some of the most fantastic places only exist within the pages of books, the frames of films, the panels of comics, even the lyrics of songs. You can't buy a plane ticket to any of these cities. You can't drive there in your car. You can only catch glimpses by watching your favorite show, or rereading your favorite novel.

Some of these places are so thoroughly imagined by their creators, you forget they aren't real. Some leave gray spaces that only your imagination can fill in. And as cool as some of these may be, there are a handful you wouldn't want to be caught dead in. In that way, the pages of a comic or your computer's monitor are about as close you want to get. Regardless, they all leave their mark on the individuals who wander their streets.

Here are the 50 coolest fictional cities.
