Following the language Georges Bataille adopted when studying the ritual traces of animal sacrifice found in Paris’s abbatoir at la villette, this project proposes exploring the potential of a “formless” architecture in similar response to proposing an extended museum around Rome’s ex-mattatoio. The project proposes to create a series of interventions connecting the proposed open-air museum in Testaccio. By delineating a path through the existing fabric and weaving disparate spaces into a comprehensive whole this project addresses properties of repressed urban desires through bracketing and framing the industrial ruins surrounding Monte Testaccio. Each intervention comments on the concept of the “architectural event” and the figurative curtain lifting alerting the common city-dweller to the buildings or events surrounding them. In Rome, grand gestures are standard fare, creating a sense of overexposure that seems to result in less awareness about the city they live in. My proposal will encourage Romans to explore and experience the ex-mattatoio in radically new ways, as charged itineraries are mapped and crisscrossed through “formless” shapes that resonate with the historic and haunting aspects of the site.
