This essay explores Austin's Hope Outdoor Gallery as a form of social control. Hope Outdoor Gallery is an outdoor museum similar to the legendary 5 Pointz in Queens, N.Y., showcasing the works of graffiti and street artists. Castle Hill-as local artists and Austin natives call it, first opened in 2011 during Austin's South by Southwest (SXSW) conference. Since its first launch, Castle Hill's walls have exhibited the works of hundreds of artists, including the work of renown Los Angeles-based street artist Shepard Fairey, known for his "Obey" André the Giant has a Posse, and his Obama Hope poster. This essay provides a critical analysis of Castle Hill as a spatial form of social control. Drawing from in-depth interviews with local street artists, as well as the experiences of the researcher in the field, this work discusses how the institutionalization of "legal walls" for aerosol art pigeonholes street artists and keeps graffiti away from the streets. This essay argues that, by providing a safe space for spray painting, Castle Hill alienates street art from public spaces and thus alienates street artists from their subcultural roots.
