[4][5][6] The synagogue continued to deteriorate until 1962, when the city council bought it from the National Office of the Hungarian Israelites, according to contemporary historian, János Németh.

[7] Multiple parts of the government and skilled volunteers worked to rebuild it between 1963 and 1964, and on September 28, 1964, it was inaugurated as the House of Technology (Hungarian Technika Háza), and became the home of the city's Organization of Technical and Natural Science Associations (MTESZ), which was founded on the same day.

After that, the office of the Ister-Granum Euroregion operated there for a short time, until in 2008 it moved to the building of the County Hall of Bottyán János Street.
