A museum preserves and exhibits this. Sometimes the building is an exhibit itself, if it is built by an famous architect, or if it is of historic relevance.
But what if the exhibition design becomes historic as well? In 1976 the famous functionalist German graphic designer Otl Aicher made the corporate design of the "Historisches Museum Frankfurt". From pictograms to displays and prospectus. Today only some fragments remain in the prehistoric and numismatic department.
The clear functional design of the Ulm School (founded by Inge Scholl, Otl Aicher and Max Bill) already vanished from daily life, and my generation could experience it only by books or some exhibits. In this museum somebody can see the perhaps last remaining original exhibition made by Otl Aicher. It's future is unsafe because the geat parts of the Museum will be teared down and replaced by a new building.
