In the beginning of the 20th century, Prussian authorities of
Bromberg decided to have a
realschule built on the outskirts of then city downtown. The commissioned architects, Carl Zaar and Rudolf Vahl, had just completed together in 1901 the
Słupsk Town Hall in the nearby
Prussian
Province of Pomerania within the
German Empire. Carl Zaar (
Köln, 1849-
Berlin 1924), was a pupil of architect
Julius Carl Raschdorff, one of the leading German architects of the second half of the 19th century. He was a supporter of German
historicism and designed the
Berlin Cathedral. Rudolf Vahl had a construction engineer background and came from Berlin. In the late 1910s, the
wing onto Paderewskiego street has been rebuilt. The building housed the city
realschule from its inception till October 15, 1921, when it housed the Polish Municipal High School of Mathematics and Natural Sciences (), then at Paderewskiego street. The edifice housed in 1925, the Municipal Music Institute, newly established, and headed by the Poznań pianist Zygmunt Lisicki. In the 1930s, it became a High school for boys, . During
Nazi occupation, the building served, among others, as a military hospital. After the
war, the edifice housed vocational schools: • The Technical school of the Posts and Telegraphs Ministry; • The Technical railway school -
School Group Nr.13 , which was disbanded in August 2007. Since 2005, the Copernicanum building has been the property of
Bydgoszcz University, or UKW . Between 2005 and 2007, heavy restoration works, including upgrades to current standards, were performed over the facility, allowing UKW to house the Institute of Mechanics and Applied Informatics, . ==Architecture==
