Areas and methods of work
Investigating a prison or massacre can take years and may require interviewing dozens or hundreds of people and analysing large collections of documents. For that reason, Matar does not reduce an investigation to a final article. With the Prisons Museum, he works to build an integrated dossier that brings together the site, the 3D tour, documents, testimony, a timeline and the written investigation.
Records are tested against testimony, photographs, open sources and field documentation. A document is not treated as true because it is official, nor a testimony as complete because it is direct; each source is read for what it reveals, what it omits, and where it agrees or conflicts with other evidence. The Prisons Museum has published seven major investigation dossiers in Syria and Iraq, with others still in progress.
Matar works on episodes of contemporary Syrian and Iraqi history whose records remain incomplete or fragmented. He begins with the traces an event leaves behind — documents, testimony, photographs, buildings and media records — then arranges them in time and connects people, institutions and places.
Historical reconstruction is not meant to produce a closed final narrative, but to show what is known, how it is known and where uncertainty remains. When a document conflicts with testimony or with what the physical site makes possible, the conflict is examined rather than hidden or resolved arbitrarily. Matar and the Prisons Museum team have collected hundreds of filmed testimonies related to prisons, massacres and disappearance.
For Matar, an archive is not a place where material is deposited after an investigation; it is part of the investigation itself.
Documents, photographs, testimony and audiovisual materials are preserved with their context: source, date, producing institution, and the people and places they mention. These elements are then linked so they can be searched and revisited with new questions. In the work on ISIS alone, the team preserved more than 70,000 documents and records alongside hundreds of testimonies and field materials. After the fall of the Assad regime, the archive expanded to include large collections of Syrian official records. Sensitive material remains subject to access and protection rules.
Matar treats place as part of the evidence. Since 2017, Prisons Museum teams have documented detention sites and crime scenes using high-resolution and 360° photography, drones, plans and aerial imagery before sites change or disappear.
After a site is recorded, its structure is compared with testimony and related documents. This helps identify the uses of rooms and corridors, test spatial claims and understand changes to a building over time. 3D reconstruction is not used as illustration or to simulate a detainee’s experience, but to create a navigable spatial record that can be linked to testimony, documents and timelines and used in investigations, research, exhibitions and legal work.
Documentary film was one of Matar’s earliest tools for recording events, people and places beyond the limits of the news cycle. Image, sound, interview and sustained observation preserve details and experiences that cannot be reduced to written information.
As the work developed toward investigation and archives, film ceased to be a separate track. A filmed interview can become part of the archive, field video part of spatial documentation, and visual testimony a source linked to a document, an investigation or a 3D tour. Film is therefore not only a way to present research, but one of the tools through which research is produced.
One question remains after an investigation and archive are built: how does this knowledge move into public space?
Exhibitions can place documents, testimony, reconstructed sites and timelines in a single space that the public can enter and read. They are treated not as the end or promotion of an investigation, but as another form of interpreting and publishing the material. Since 2024, Prisons Museum work has appeared in public spaces in London, Paris, Damascus, Berlin and elsewhere. In each exhibition, archival materials are reorganised around the site and the question so visitors can encounter not only what happened, but the evidence on which that knowledge rests.
