The University of Debrecen, which was established 1912, considers itself as an heir of the Reformed College of Debrecen. This can be seen in the visual concepts (architecture, clothing, using of objects of the College etc.), which date back to the old traditions of the Reformed College. In 1938, the University Council took the decision to build lead-glass windows in the Aula of the Main Building, remembering the old university-connections of the Reformed College with Geneva, Zurich, Utrecht, and Wittenberg. This article aims to analyse the motives of the University Council for choosing these universities as the most important old connections of its predecessor and to find out if windows were thought to be as “loci memoriae” or rather as a gesture to the important living connections.
