A small historical exhibit located in the gallery takes visitors through the history of the brand. Diplomas issued by court purveyors, medallions, and certificates that bear witness to the exceptional quality of the product in many countries of the world for over two centuries are featured next to the oldest of perfume flasks. The variety of products related to Echt Kölnisch Wasser become apparent in the glass display cases; the development from Aqua Mirabilis to the world-famous perfume.
