The Casimirianum grammar school, founded in 1605 by Duke Johann Casimir, is one of Coburg’s most important Renaissance landmarks.
Initially envisioned as a state school and a counterpart to the University of Jena, it has remained an enduring symbol of the duke’s commitment to education. A statue of Johann Casimir adorns the building's facade, commemorating the school's founder and his vision. Notably, the Casimirianum boasts the preserved Bibliotheca Casimiriana, a treasure trove of scientific literature that forms part of the Coburg State Library today. Among its distinguished students was Johann Caspar Goethe, father of the famous poet Johann Wolfgang von Goethe. The Casimirianum continues to serve as an educational institution, maintaining its historical significance.
