Within the framework of the World Heritage convention, UNESCO (United Nations Educational, Scientific and Cultural Organisation) defined ten criteria for the inclusion of sites in the world heritage list. Four of these criteria applied to natural assets, while the other six criteria applied to cultural assets. Sites are considered to be of extraordinary global significance if the World Heritage Committee determines that they fulfil one or more of these criteria.
The outstanding universal significance of the Fagus Factory relates to the modern architecture of Walter Gropius, which makes the factory stand out at the international level.
The structure signifies the innovation associated with the curtain wall, which takes both the vibrancy and the brightness into consideration. It also takes into account the interests of the working world, in terms of productivity and the humanisation of working conditions and combines these interests. The idea that architecture and design constitute a critical factor for the quality of human life was formulated for the first time by the Fagus factory and was handed down to subsequent generations.
The Fagus Factory was added to the list of world heritage sites on the basis of criteria 2 and 4.
Criterion 2: The Fagus Factory represents the moment associated with a significant intercommunion between different generations of German, European and North American architects, which constituted the basis of a rational and modernistic architectural style. It represents the synthesis of these technical, artistic and humanistic influences and it also influenced many other architectural works in its capacity as the origin of the Bauhaus movement.
Criterion 4: With regard to the manifestation of the modern style within the area of architecture, the Fagus Factory is, along with its architect Walter Gropius, well-reputed on the international stage. It exemplifies the innovative nature of the curtain wall, which is characterised by its vibrancy and brightness. It is a vivid expression of the functionality of the industrial complex and serves the interests of productivity and the humanisation of working conditions. It represents the unification of the concepts of industrial aesthetics and design-related factors.
