This fine example of Hungarian modernist architecture from the early 1940s is located at Katona József utca 4/D, in the 13th district of Budapest. Designed by György Kudelka and Gábor Simó, the building was constructed in 1942. In 1944, it became a yellow-star house, serving as a compulsory residence for Jews in Budapest who were subsequently either sent to the ghetto or to designated “protected houses.”

The list of these yellow-star houses was issued by the Mayor’s office on June 24, 1944, giving the Jewish population, constituting almost 25% of the city at that time, only a few days to relocate. The relocation process was overseen by the police and the Jewish council, with a yellow star prominently displayed on these designated houses. In November 1944, the Jews were further moved to the ghetto in the 7th district of Budapest. Some were allowed to go to the “protected houses” within the “international ghetto,” which were buildings under the protection of neutral states.
