The aim of this master thesis is the virtual reconstruction of the synagogue in Oberwart/Felsöör, a building that no longer exists in its originally planned form and use. The temple was built in 1904 and used by the Jewish community until the annexation of Austria by the NS regime. After only 34 years of existence, the building was converted into a fire station. Since 1997 the former synagogue has been used as a Central Music School. Because of these rebuilding actions, almost none of the original structure of the historical design was preserved. In the first part of this thesis, the history and the development of the Jewish community in Oberwart/Felsöör will be described in order to provide an insight into the community, which no longer exists. The second part is devoted to the building structure of the synagogue, its historical development and architecture, and to comparable synagogues. Subsequently, the operation method in the virtual reconstruction process will be described. This includes the documentation of the research phase and the materials determined in that process as well as the modelling of the building using CAD (computer-aided design) -software. In the final part, the visualization procedure of the virtual model and the results will be illustrated. The renderings are intended to give an impression of what the synagogue in Oberwart/Felsöör looked like in its original appearance.
