The synagogue was bombed by the Hungarian pro-Nazi Arrow Cross Party on 3 February 1939. Used as a base for German Radio and also as a stable during World War II, the building suffered some severe damage from aerial raids during the Nazi Occupation but especially during the Siege of Budapest. During the Communist era, the damaged structure became again a prayer house for the much-diminished Jewish community. Its restoration and renovation started in 1991, financed by the state and by private donations, and was completed in 1998 (see below).
