A new form of investigative practice that uses architecture as an optical device to investigate armed conflicts and environmental destruction. In recent years, the group Forensic Architecture began using novel research methods to undertake a series of investigations into human rights abuses. Today, the group provides crucial evidence for international courts and works with a wide range of activist groups, NGOs, Amnesty International, and the UN. Forensic Architecture has not only shed new light on human rights violations and state crimes across the globe, but has also created a new form of investigative practice that bears its name. The group uses architecture as an optical device to investigate armed conflicts and environmental destruction, as well as to cross-reference a variety of evidence sources, such as new media, remote sensing, material analysis, witness testimony, and crowd-sourcing. In Forensic Architecture, Eyal Weizman, the group's founder, provides, for the first time, an in-depthintroduction to the history, practice, assumptions, potentials, and double binds of this practice. The book includes an extensive array of images, maps, and detailed documentation that records the intricate work the group has performed. Traversing multiple scales and durations, the case studies in this volume include the analysis of the shrapnel fragments in a room struck by drones in Pakistan, the reconstruction of a contested shooting in the West Bank, the architectural recreation of a secret Syrian detention center from the memory of its survivors, a blow-by-blow account of a day-long battle in Gaza, and an investigation of environmental violence and climate change in the Guatemalan highlands and elsewhere. Weizman's Forensic Architecture,stunning and shocking in its critical narrative, powerful images,and daring investigations, presents a new form of public truth, technologically, architecturally, and aesthetically produced. The practice calls for a transformative politics in which architecture as a field of knowledge and a mode of interpretation exposes and confronts ever-new forms of state violence and secrecy.
