This article has grown out of a larger project on representations of subterranean space in the modern city. It explores the meanings of the “utilidors,” the underground infrastructure of the Magic Kingdom, within the broader experience of the space of Walt Disney World. It relates this experience to a particular mode of representing the modern city as divided between its respectable, aboveground spaces and its hidden, underground spaces. The author concludes by suggesting some of the insights the power of Disney’s spatial divisions can provide in thinking about current images of the city as simultaneously a site of “Disneyfication” (e.g., the new Times Square) and as a place of ruin, crime, and decay.
