This essay employs literary and field research to examine city of Val d’Europe (France), its history as part of the “ville nouvelle” of Marne-la-Vallée, its development as a collaboration of public planning agency EPAFrance and The Walt Disney Company, and especially its relationship to the neighboring Disneyland Paris theme park resort. Using the examples of the city’s Lakeside and Studios District, the essay argues that the theme park and the city are related not only via the technique of theming but, more specifically, by the choice of theme or architectural styles, with the result that the line between private leisure space and public urban space becomes blurred. The article also suggests analyzing Val d’Europe in the larger context of “Disney Cities,” a concept that encompasses Disney’s theme parks and resorts in the U.S., Europe, and Asia, particularly the (past and present) three-dimensional depictions of urbanity contained therein, as well as Disney’s various (realized and unrealized) urban development projects, both within and outside its resorts.
