Enacting an emancipatory historical ceremony, this project addressed the 1991 foundational event of the never-built Armillary Sphere. By recreating the protocol of a "first stone" ceremony—traditionally a rigid institutional ritual—we transformed it into a fictional popular festival on a plot of land that was never consolidated. Through archival reconstruction and community participation, the intervention treated this "false start" as a ritual of belonging, allowing residents to invent their own tradition and reclaim a space left vacant by failed urban speculation.
