In the early 1970s, a school of architecture and a concentration camp appeared at the Ritoque beach, just north of Valparaíso, Chile. Situated three miles apart, they never acknowledged each other's presence. Nonetheless, their occupants formed communities that used a similar repertoire of games, events, and performances to create real and imaginary spaces. Faculty at the school deployed these activities to form a utopian enclave, freeing students and themselves from the strictures of normative education and practice, while limiting their political agency. In contrast, the prisoners of the camp transformed their enforced isolation into active political resistance.
