In Gothic: A Romance, a 1990 Batman story from the pages of Legends of the Dark Knight, Batman finds himself battling a satanic monk who attempts to kill everyone in Gotham City, and offer their souls to the devil in exchange for immortality. His plan rests on Gotham’s specific architecture, utilizing a series of cathedrals designed to place the stress of their weight up towards heaven. Batman eventually stops him, but this poses an interesting question: If the cathedrals of the city point up to heaven, then where is Gotham? The answer of course, is hell.
Gotham City is Hell.
