Müritzeum

The Müritzeum is a visitor centre and nature discovery centre for the Müritz National Park, located on Lake Müritz, near the town of Waren in the north German state of Mecklenburg-Vorpommern.

The concept of the visitor centre is to have an enjoyable and interactive science-based approach to the themes of nature and regional history. The exhibition and aquarium area is devoted to the presentation of the flora and fauna and history of the Mecklenburg Lake District. Its centrepiece is the largest aquarium for native freshwater fish in Germany, with a capacity of 100,000 litres.
