Within the cultural and historical ensemble of the old centre of Zrenjanin stands the Palace of Justice (courthouse and prison), built between 1906 and 1908. In the competition held by the Ministry of Justice in Budapest, the first prize for the design of the county court and prison building went to the Budapest architect Sandor Ajgner. By its purpose and size, the building testifies to the growing role of Great Bečkerek as the administrative centre and regional seat of Torontal County.
The Palace of Justice in Zrenjanin was placed under the protection of the law of the Republic of Serbia and was declared a cultural monument in 1972.
