Collecting, preserving, researching, exhibiting and communicating are the five cornerstones of museum work. In this context, preservation is of central importance. Museums maintain, secure and protect the objects from destruction, sinking and decay. To do this, things are stored and inventoried in a depot, a safe place with the best possible climate. Just as the archive functions as the city's written memory, the museum primarily preserves material tradition.

Miltenberg has an extraordinary collection that is certainly one of the most important in Lower Franconia. The origins of the collection go back to civic engagement in the 19th century. In the last 30 years, the collection has grown considerably, especially in terms of quality. The reason for this is a systematic expansion according to museological criteria and the specifications of a collection concept. A suitable building is required for orderly, flawless conservation and safe storage of archive and museum items.

In 2019, after a long planning phase, the new central depot at Mainzer Tor was opened. The complex combines the municipal archive, museum depot and youth center. In addition to the actual storerooms, the rooms used by the museums also include offices, a quarantine room and a workshop. Here are around 90 % of the Miltenberg collection.


The total cost of the project was around 9 million euros, 65% of which was covered by the sponsors. The entire construction was generously supported by the government of Lower Franconia as part of the urban development program. The prerequisite was the joint use as a museum depot, city archive and youth center as well as the integration of the historic Mainz tower.

The furnishing of the work and storage rooms used by the museum was also funded by the state office for non-governmental museums in Bavaria and the cultural foundation of the Lower Franconia district.
