About us

We, the BUND (Bund für Umwelt und Naturschutz Deutschland, Landesverband Rheinland-Pflanz e.V.), are supervising the educational concept of the visitor and information centre Mosellum since February 2019. It is all about fish migration, shipping and electricity generation. The operator of Mosellum is Struktur- und Genehmigungsbehörde Nord (SGD) and it is sponsored by Ministerium für Umwelt, Energie, Ernährung und Forsten (MUEEF) in Rhineland-Palatinate. It was built on the wall of the old fishpass for Bundesgartenschau (BUGA) 2011. The exhibition is located at the riverside of the Moselle next to the last weir before Moselle flows into Rhine.


The exhibition’s goal is to teach visitors of all ages the ecological functions of the Moselle. It also promotes a sustainable way of thinking in relation to economy and ecology. In Mosellum visitors can discover the world of fish and experience it live, with a lot of information and exhibits. Environmentally related gaming tables, crossword puzzles and hands-on exhibits enable young visitors to experience the contents of the exhibition in a playful way. Our “Blue Classroom” provides an extracurricular place of learning which can be used for lessons, workshops and other events.


The visitor centre Mosellum is dedicated to the topics of fish migration, shipping and electricity generation. It is divided in four different exhibition areas: Shore, Ship, Underwater and Outlook. The exhibition is barrier free and you will find the contents in English and German.

At the “Shore” level, visitors can go on a journey and discover the Moselle valley. The “Shore” focuses on the region’s biology, geology and history. If you follow the course of the Moselle, you will see how it changes. From its spring in the Vosges Mountains to its mouth into the Rhine River in Koblenz. The exhibition also reflects the diversity of the region’s many habitats. The “Shore” shows plants and animals in and along the Moselle, and shows which of them are rare, common, indigenous or invasive.

The “Ship” exhibition explores the tensions between economic and environmental interests and presents some preliminary solutions to this multifaceted conflict. The Moselle has been used as a transport route for 2,000 years. It has gone through a long period of developments until now, where it is dammed and used to generate renewable electricity. These developments have greatly changed the entire Moselle ecosystem.
On the “Underwater” level visitors can learn interactively about typical fish of the Moselle and the lifecycles of two long-distance migratory fish – salmon and eel. With a little luck, you might spot one or two of these fish “live” in the fish pass.

Furthermore, the Mosellum offers a terrace with an outlook over the river mouths of Moselle and Rhine. Visitors can enjoy a bird’s eye view of the fish pass and watch wildlife in and around the Moselle. On this level you can also find the Ausonius Studio which can be used as the “Blue Classroom”, for workshops or conferences.

Our target groups are people of all ages. The Mosellum is free of charge to enable the access to education for everyone. Additionally, the exhibition is barrier-free and texts are available in German and English. We are welcoming school classes and youth groups as well as all other individual visitors and groups to introduce them to the exhibition with age-appropriate concepts.


Our values stand for openness towards our visitors and tolerance towards people and environment. Treating each other with respect is important internally as well as towards our visitors. We want to strengthen and support the diversity of people, flora and fauna. 


We are a young, committed team from the field of environmental sciences and are happy to benefit from the exchange with visitors. Our interactive exhibition not only appeals to adults, but thanks to our educational concept also arouses the interest of young visitors. In addition to our on-site visitor supervisors, we also work with several speakers to support and develop workshops in order to expand our educational offer with environmentally relevant topics.

Internally, we work together with the Struktur- und Genehmigungsdirektion Nord (SGD), the Bundesanstalt für Gewässerkunde (BfG), the Internationalen Kommission zum Schutz des Rheins (IKSR), and the Ministerium für Umwelt, Energie, Ernährung und Forsten Rheinland-Pfalz (MUEEF). There are also cooperations with the WasserWissensWerk and the University of Koblenz, as well as with many other cooperation partners.
