Prisons Museum
2017 — OngoingPrisons Museum grew from a practical question: how can the physical, documentary and human traces of detention be preserved before they disappear, and how can those traces be connected without forcing them into a single source or narrative?

Question and approach
The work began in 2017 within AlShare Media Foundation while we were searching for colleagues and relatives disappeared by ISIS. Former detention sites contained names scratched into walls, physical traces, records and local memories that were already at risk of being lost, looted, demolished or absorbed into new uses.
The question gradually moved from the fate of a single person to the structure of detention itself: how a site functioned, who moved through it, how an order became a procedure, and what could be learned by reading a building together with testimony and records. The method therefore developed across site investigation and forensic photogrammetry, document and testimony archives, 3D reconstruction, investigative research and databases that map relations between people, places, documents and events.
The museum is not the end point of this process. It is one public form the research can take. The same body of evidence can also support families searching for the missing, journalistic and academic research, legal accountability and longer-term public history. The methodology is survivor-centred: consent, dignity, security and the ability of survivors to shape how their knowledge is used are part of the evidentiary process itself.
Role in the work
Matar founded the institution and leads its investigative and editorial direction. The methodology itself is collective: it is developed and carried out with journalists, field documentarians, architects, archivists, technologists, researchers, lawyers and survivor communities.
