The image of Europe has been forever affected by the Holocaust in the 20th century. Many Jewish communities disappeared, their religious buildings were destroyed and torn down and with them the image of old Europe. Among them is the Great Synagogue in Vukovar in eastern Croatia. The religious building was built according to the plans of the Viennese architect Ludwig Schöne, who was involved in the planning of several synagogues across the Austro-Hungarian Empire and was one of the most prolific architects of his time. This thesis deals as part of a larger project with the virtual reconstruction of the demolished synagogue in Vukovar. Through localised research and modern computerised programs, a virtual model of the buildings is created and preserved. As a result, the building, which one might have thought lost, can be experienced by a broader audience. As many of the documents were destroyed or lost in the wars, the focus was on the reconstruction with the help of alternative tools that enable an accurate geometrical model with the use of images and a few written descriptions. At the beginning of this work, a brief historical overview and the most important milestones of the region are given. They are important for the understanding of the historical context in which the hermitage of the Jewish population and the construction of the synagogue began. The second chapter discusses the synagogue and its architect. A biography of the architect, Ludwig Schöne, is followed with a short description of the first synagogue, which is characterised by its unique architecture that cannot be found anywhere else in Croatia. Following this is a description of the location and architecture of the great Vukovar Synagogue. The main part of the work deals with the computerized reconstruction itself, starting with the research phase were the documents that served as a template are illustrated and ending with the design steps necessary to finish the 3D model. The last chapter illustrates the results of the reconstruction, which were created using the Atlantis rendering program.
