Research on Jewish heritage sites in Europe broadly involves the evaluation of synagogue architecture under threat. Seeking to re-enhance the original state of such sites, related studies have focused on limited material and theoretical data. Therefore, the specific identity of those structures is gradually vanishing from collective memory. The last decades have seen a renewed interest in working out an alternative conception of remembrance, focusing on a representation of memory rather than the preservation of materiality. Defining tools and methods for Jewish heritage preservation is a challenging issue, as its self-identification is generally framed as an intangible expression. The article constitutes an attempt to confine certain figurative specificity of Jewish identity that synagogue architecture demonstrates and exemplify it as a potentiality for reinterpretation and construction of coherent memory discourse through new architectural form. Firstly, this paper refers to the philosophy and formal principles of Jewish religious space. Secondly, drawing on the selected architectural cases of American Congregation architecture, this article evaluates formal spatial and artistic reflections on vanished synagogues from Eastern Europe. Finally, the study examines the creative link between formal articulation and symbolic abstraction related to Jewish architectural tradition, where the heterogeneity and constant search for meaning reflected in a structure, a form, and a symbol are characteristic points of Jewish identity.
