The photographs that did not survive in the building
What remains of it is paper: the measured drawings produced by Warsaw University of Technology students in the 1920s, and a set of photographs held today by the YIVO Institute for Jewish Research in New York. Between them, these two bodies of material constitute the building's surviving form. Where the drawings give dimension and geometry, the photographs give surface, light, and the kind of detail that a scaled line cannot carry.
YIVO — the Yidisher Visnshaftlekher Institut, the Institute for Jewish Research — was founded in Vilna in 1925 and relocated its operations to New York in the early 1940s. Its photographic holdings on Polish Jewish communities represent one of the largest concentrations of pre-war visual documentation in any archive. The Zabłudów material within those holdings is modest in quantity but specific in what it records: exterior elevations of the synagogue's log walls, roofline details, the entrance porch, and aspects of the interior, including the painted decoration of the ceiling and walls that the measured drawings could represent only in outline.
What the photographs record that a drawing cannot
A measured survey produces plan, section, and elevation drawings — scaled orthographic representations that fix dimensions with precision. What a pencil line on paper cannot fix is the texture of adze-worked timber, the weathering pattern on a shingle course, or the chromatic layering of interior paint applied across several centuries. The YIVO photographs carry that information, at whatever resolution pre-war photography permitted. They show the log walls in the condition they had reached by the 1920s or 1930s: the checks and splits in exposed timber, the way the roofline sat against the sky, the depth of shadow in the entrance porch that indicates both the projection of the overhang and the thickness of the wall beneath it.
For reconstruction work, this is material of a different kind from the drawings but not of lesser value. When Handshouse Studio undertook the reconstruction of the Gwoździec synagogue ceiling for the POLIN Museum of the History of Polish Jews, photographs were used precisely where survey dimensions were absent or ambiguous — to verify the visual character of painted motifs and to confirm spatial relationships between elements. The Zabłudów photographs serve an analogous function: they are not a substitute for dimension, but they adjudicate between interpretations when a line on a drawing admits more than one reading.
The photographs as the building's present tense
There is a practical distinction between using photographs as historical evidence and recognising them as the building's current state of existence. The Zabłudów synagogue no longer stands. The log walls documented by Warsaw University of Technology surveyors, the shingle roof, the painted interior, the bimah — all of it is gone. What the YIVO photographs show is therefore not a record of something still accessible for cross-reference. It is the thing itself, in the only form the thing now takes. Each print in the archive is a structural member of the building's surviving documentary corpus.
This has consequences for how the material is used and how its custody is understood. The YIVO Institute's online collections provide digitised access to portions of its photographic holdings, making the material available to researchers at institutions including the Museum of Folk Architecture in Sanok, where reconstruction work drawing on Zabłudów documentation continues. Polish State Archives in Białystok hold parallel administrative material, but for the visual record of the building's fabric, YIVO's holdings remain the primary source. Researchers working on the reconstruction treat each photograph not as illustration but as evidence — examined for what it shows about corner joinery, roof pitch, and the relationship of the entrance porch to the main volume, in the same analytical register as a section drawing or an elevation.
The photographs did not survive by design. They survived because they were already elsewhere when the building was destroyed.
