The second think tank of the DFG focus program Cultural Heritage Construction addressed the concept of authenticity, a central standard of value in the field of historic preservation. Authenticity has become an omnipresent term, which is basically characterized by one thing above all: it has a positive connotation, it is quickly associated with terms such as “credible,” “genuine,” ” united,” perhaps also “truthful. In any case, authentic is good. This has also been true of historic preservation for almost 60 years, because in 1964 the Venice Charter elevated the concept of authenticity to the central value standard of historic preservation.
The building constructions of high modernism have so far received little attention in the countless discourses on this topic. The equally significant and blurred category of authenticity was therefore elevated to the annual topic 2022 of the SPP 2255. In the think tank, renowned experts traced the challenges, criteria and processes of concrete handling in the special field of ultra-modern building constructions. On closer inspection, the ‚guiding star of monument preservation‘ proved to be a fragile and dynamic construction, especially here.
In addition to sharpening the content of the term in its application to ultramodern constructions, the think tank also served to develop a common basis of understanding about a central term of monument preservation between the broadly based disciplines in SPP 2255. In this context, it was also necessary to clarify the extent to which this conceptual model developed in the monument sciences can be made useful at all as a category for dealing with the cultural heritage of construction.
The think tank „Authenticity“ of the SPP 2255 was held as a public event in the auditorium of the Bauhaus building in Dessau.

We wish you all a Merry Christmas and good luck, health and many new successes for 2022.
Workshop Incomplete
Berlin
The workshop incomplete of the DFG Priority Program Cultural Heritage Construction addresses the borderline between contemporary modern additions and authentic restoration as well as the fascination of ageing as a measure of value. High-modern building constructions offer special challenges, criteria and processes that can also be found in the considerations analogous to the field of art restoration. The focus here is on developing a different view of the interrelationships and the joint communicative exchange of ideas.
Merry Christmas and a Happy New Year
Cottbus
How good it was to finally be able to exchange ideas in person again! Communication in the second year of our DFG Priority Program was characterized by a wide range of encounters, from common ground and cluster workshops to think tanks and annual meetings.
Thank you for your powerful commitment!
The Cottbus Head Office wishes all contributors, supporters and friends of SPP 2255 health, happiness, joy and success in their work in 2023!
Merry Christmas and a Happy New Year
Cottbus
The first funding phase of SPP 2255 is coming to an end, and we will be starting the second at the beginning of the year. Three more years of the Cultural Heritage Construction Research Network lie ahead of us. Some projects are coming to an end, others are being added. We would like to thank all those with whom we were able to work in the first phase for exciting encounters, multi-layered suggestions, valuable insights and their often inspiring commitment to the common cause – the interdisciplinary process of valorizing the cultural heritage of construction.
For 2024, Team Cottbus wishes both old and new contributors and supporters health, happiness and joy in their work!

Workshop “History of construction technology and history of technology – cognitive interest, topics and methods in dialog”
Stuttgart
The history of building technology and the history of technology are sister disciplines. However, there is hardly any exchange. Scientific contacts, joint conferences or even projects are rare exceptions. There is an unmistakable difference in their research interests, topics and methods. But this is precisely where the potential of the encounter lies: the different emphases can also be seen as mutually enriching. There is much to learn from each other!
Rediscovery of a key work by Peter Behrens thanks to SPP 2255
Dessau-Roßlau
During the second annual meeting of the SPP 2255 in Dessau-Roßlau, the participants also visited on October 13, 2022 various historical constructions in the Dessau-Mitte industrial park in the course of a field trip prepared by Axel Schuhmann (Anhalt University of Applied Sciences). One of its preserved halls made a particular impression on the participants, yet there was hardly any information available about it – for example on the construction period or the planners responsible.
Subsequent research led to a surprising discovery: the building is a supposedly lost work by the architect and designer Peter Behrens (1868-1940), an exceptionally important figure for the development of modern architecture.

WORKSHOP OF THE SUBPROJECTS C3, C4, D1, D2 AND E1 – TYPIFIED GDR STRUCTURES AS HISTORICAL SOURCES OF ENGINEERING DESIGN
Weimar
The GDR produced highly typified load-bearing structures based on standardised building elements, which were in turn combined in type buildings. The workshop will focus on the phenomenon of state-led building typification in East Germany, with a consideration of West German type building for contextualisation. In addition to an insight into materials, constructions and development mechanisms, the constructive side of building in the GDR will be addressed and its worthiness of preservation discussed, away from the classical history of architecture and urban development.
The workshop will take place from 29.-31 3. 2023 at the Bauhaus University Weimar. A one-day excursion on 31. 3. will explore selected type buildings.
Denkwerkstatt 2023: High Modern Age adapt to the loads

Conference “Steel on New Paths”
Stuttgart
In high modernism, steel, along with reinforced concrete, was not only a building material whose material properties made it possible to realize architectural visions, structural innovations or infrastructural systems that had previously been considered impossible. In this context, the material was also connoted with a symbolism that made it an integral part of the contemporary promise of progress across all systems.
4. WORKSHOP OF SUBPROJECTS A1 AND A2 – “RAILWAY BRIDGES – CONSIDERATION OF MONUMENT PRESERVATION CONCERNS IN COMPARISON BETWEEN DB AND SBB”
Dresden
The Swiss Federal Railways (SBB) can look back on a long tradition of taking monument preservation concerns into account in planning practice. Firmly established structures such as the SBB Fachstelle für Denkmalpflege or the SBB Historic Foundation have proven to be very helpful. What can the railway and monument preservation in Germany learn from this?
Common Ground #3 – TragWERK

SUMUPLAB 2022: AIRCRAFT HANGARS IN COTTBUS
Cottbus
The “strategy and method laboratories” (SuMupLABs) are one of the central event formats to promote interdisciplinary exchange in the SPP 2255. They are explicitly aimed at the processors in the individual sub-projects of the SPP.
The SuMupLAB 2022 takes the participants to the former airfield Cottbus-Nord. The site, which was used by the military from 1933 to 2003, is currently undergoing forced expansion into a commercial location in the context of structural change in Lausitz. This raises crucial questions about the future authenticity of an ensemble of five aircraft hangars that are unique in Germany.
