A large exhibition area is the comprehensive collection of Münden faiences from the 18th/19th cent.
- An extensive antiquities collection of historical finds made during the excavation of the building pit for the observation tower in 1881 on the Tillyschanze. The space in the lower tower room of the Tillyschanze soon proved to be too small for the constantly growing collection of antiquities. In 1887, the collection comprised around 1800 objects.
- A large number of plaster models by the Berlin sculptor Prof. Gustav Eberlein, who lived in Münden, had been brought to Münden Castle by the artist from 1893. The "Eberlein Section" was additionally decorated by the artist himself with hand drawings and paintings. The restoration of Münden Castle, which was undertaken by the Prussian Department for the Preservation of Monuments, opened up the prospect of appropriate premises for these collections, which varied in size. The transfer of most of the antiquities collection from the observation tower of the Tillyschanze to the castle took place in October 1897.
At the same time, an entire railway carriage with numerous unique plaster models by Eberlein arrived in Münden from Berlin. More works followed in the spring of 1898, and Eberlein continually added to "his" museum with the latest creations in sculpture, architecture and painting. Today, a total of over 900 works of sculpture, painting and writing are known.
Exhibition of Roman finds from Hedemünden
A new permanent exhibition brings the history of the Hedemünden Roman camp to life. In the years between 11 and 9 BC, the military camp was built as a supply base while Emperor Augustus led his campaigns from the Rhine into the Germanic regions as far as the Weser and Ems rivers. Excavation and research results from the Roman military camp, which was only discovered in 2003, are presented with over 200 finds. They bear witness to life in the Roman camp. Reconstructions of a legionary's tent and equipment, as well as varied activity stations, invite visitors to discover and participate.
