Forensis reactivates the Latin root of forensics, returning evidence from the closed courtroom to the wider forum of political contestation. Its iconic idea is that buildings, territories, images, sound, ruins, digital traces and landscapes can become witnesses when interpreted through architectural, aesthetic and scientific procedures. The theoretical contribution is the formulation of forensis as critical practice: an inversion of the forensic gaze from state policing toward the investigation of state, corporate and environmental violence. Methodologically, the volume assembles casework, essays, visual analysis, legal reflection and media investigation across zones of war, occupation, migration, ecological damage and contested jurisdiction. Its conceptual operation is public evidencing: matter is animated into testimony through models, images, spatial analysis and forums capable of receiving dispute. The bridge to the wider field links architecture, human rights, visual culture, law, media studies and political ecology, making spatial evidence a method for constructing public truth under conditions of denial.
