Not all artworks in a museum are presented to the public; most are kept away from view and stored securely. A door in Freising conceals a room filled with artworks, safeguarded by an alarm system, with the location kept discreet for security reasons. The environment in this storage area is meticulously controlled, with a specific temperature and humidity level maintained to preserve the pieces as best as possible despite natural aging.

Art historian Steffen Mensch explains the importance of these precautions in prolonging the artworks' lifespan. While aging is inevitable, the careful management of the storage conditions can slow down the deterioration process, allowing for the artworks to be kept in an as-new condition for longer. The artworks are not merely forgotten treasures; they represent a vital part of cultural heritage that requires thoughtful preservation efforts.

This article sheds light on the often-overlooked aspect of museum collections, where much of the art is not accessible to the public eye. It highlights the delicate balance between exhibition and preservation, illustrating that behind closed doors, there exists a wealth of cultural significance that contributes to the broader understanding of history and art. Museums must navigate the dual role of sharing their collections with the public while ensuring the long-term care of artworks housed in their facilities.
