The Copernicanum is a historical building in downtown Bydgoszcz, which had been designed as a scholar building: initially a realschule, it then took the purpose of a city sciences high school and technical railway institutions. Registered on the Kuyavian-Pomeranian Voivodeship Heritage List, it is nowadays the location of a junior high school. In 1923, to celebrate the 450th anniversary of the birth of Nicolaus Copernicus, the newly created junior high school adopted his name, Copernicanum.
