Knowledge Transfer

Lost Cultural Heritage Becomes a Virtual Place of Remembrance

Karlsruhe (GER), December 2019 - The TOPORAZ project has achieved success in the renowned Leibniz competition, with the Leibniz Association’s Senate granting its approval of the effort. The world’s cultural heritage that cannot be recreated in reality is to be made available to a broad public on a sustainable basis.

Until its almost complete destruction in WW II, the city of Nuremberg had been one of Europe’s great metropolises. Its historical cityscape was regarded as a work of art. In three years of interdisciplinary collaboration, a science network led by the FIZ Karlsruhe, a company that is an institute of Germany’s renowned Leibniz Association, has developed an innovative virtual research environment that revives, documents, and visualizes that which was destroyed. The knowledge gained in the process is now to be expanded, communicated to a broad public, and made available for long-term public use.
The fire at Notre Dame Cathedral in Paris on 15 April 2019 made obvious to the world the extent to which objects of cultural heritage are historically and socially relevant, and at the same time highly vulnerable. Nuremberg's historic center played a similarly important part in European culture as the cathedral in Paris. With the TRANSRAZ project, FIZ Karlsruhe and the University of Greifswald want to make their jointly developed knowledge repository, a virtual research environment on the cultural heritage of the city of Nuremberg, available to the public for sustainable use.

Applications in the field of educational institutions and museums are planned and, based upon interest, hotspots with special information on selected places can already be set up without limits. This allows for themed tours through the historical time layers of the city, giving insight into city life in the past. The world’s cultural heritage that cannot be recreated in reality will be revived as a virtual place of remembrance. At the same time, conditions before the destruction will be systematically and scientifically investigated and documented. This has not been done before.
Renowned partners from the scientific community, the public, and the commercial sector will impart this knowledge. For example, the Nuremberg city archive plans to use the virtual research environment in the long term and complement it with its own data. This includes extensive information (texts, images, maps, sound documents) from the city's House Books of the Nuremberg Twelve Brothers Foundation project, which is currently in progress.
Another aim of this novel transfer project is the interaction with individuals. To this end, an interactive participation platform is to be added to the projected city model. The people of Nuremberg can use this platform and enrich it with their own information. They often have knowledge about their districts, houses, and apartments that is unknown to researchers. In this way, entirely new source material can be made accessible, for example, photographs from the time before WW II that show external facades or interiors prior to their destruction.
Sabine Brünger-Weilandt, President and CEO of FIZ Karlsruhe, emphasizes, "Sound and objectively verifiable knowledge about the past is essential for understanding the present, for assessing things that are different, and for generating tolerance towards everything that seems strange at first glance. Communicating this knowledge and its underlying findings is a central task for us as a Leibniz Institute for Information Infrastructure".
With regard to the Leibniz competition procedure, she continues, "Another goal of the Leibniz competition is to stimulate strategic collaboration with universities and the targeted promotion of highly qualified young scientists. I am therefore very pleased that, together with the University of Greifswald as a research partner, we have been successful in this highly competitive procedure for the second time. In addition, we can now offer a further perspective to the young team of scientists already involved in the predecessor project", which was called TOPORAZ – Nuremberg‘s Topography in Space and Time.
A joint interdisciplinary project network of FIZ Karlsruhe and the universities of Greifswald, Cologne, and Darmstadt broke new ground in 2015. Three-dimensional digital models reconstructed Nuremberg's urban space around the old city's main market square in four time levels from the Baroque period to the present (17th to 21st centuries). They were networked with numerous historical sources and images. Within three years, a virtual research environment was developed that opens up new perspectives for research into Nuremberg's history and culture over the course of time. It should now provide new insights, as well as inspiration for the interested public to participate.
