Lübeck: the chief city of the Hanseatic League 1358 - an association of towns for the protection of trading interests.
Lübeck, 14 km from the Baltic Sea.
"Liubice" (Old-Lübeck, founded by Slavs in 819); it was re-founded as "Lubeke" by Adolf II Count of Schauenburg and Holstein in 1143,
Transfer of the diocese to Lübeck in 1163 - the first cathedral in Lübeck was consecrated,
1226 Free Imperial City by Frederick II.
The Stecknitz Canal (1398) greatly facilitated the shipping of salt from Lüneburg.
Lübeck was in the 15th century the second largest city (after Cologne) in northern Germany, with 22,000 inhabitants.
After the "discovery" of the Americas, Lübeck's economy declined, and Hamburg with the connection to the North Sea became leading in trade and leading the Hanse.

Workshop: Classical Observatories and UNESCO World Heritage (IAU C.C4) and WG "Windows to the Universe - Classical and Modern Observatories"

Aims and Scope
This workshop aims to highlight the outstanding astronomical heritage represented across many European observatories and consider their merits as candidates for seeking UNESCO World Heritage status.
UNESCO awards World Heritage status to sites judged to have "Outstanding Universal Value". Astronomical connections have provided the basis for several such assessments, for instance monuments with alignments to the solstices (e.g., Newgrange in Ireland), observatories with connections to time keeping and navigation (e.g., Greenwich, UK), and mechanical models of the Solar System (e.g., Eise Eisinga Planetarium, Netherlands).
The classical form of the astronomical observatory originated in Europe with many well-preserved examples from the 17th century onwards still extant. In some cases these observatories also remain as active centres of astronomy, where research, education and/or public outreach in the sciences are conducted. These provide prime candidates for possible future nominations for UNESCO World Heritage. In Ireland the historic observatories of Armagh, Birr and Dunsink have come together to pursue such a nomination. Birr and Dunsink have just been placed on the UNESCO Tentative List for Ireland by the Irish Government (Department of Housing, Local Government and Heritage, 18 April 2025).
The intent of this session is to highlight the outstanding astronomical heritage represented across many European observatories and ask whether they be suitable for inclusion in the IAU's list of "Outstanding Astronomical Heritage" (OAH). This may also include observatories that no longer exist but have made significant scientific contributions (e.g. Gotha in Germany, Uraniborg in Denmark).
Further, we ask whether some might also be considered for future trans-national UNESCO nominations arising from several countries? While the astronomical heritage must be foremost in the applications, an extensive management plan for the site preservation is also a requirement. Within this plan the cultural and educational values of historic observatories will need to prominent. Thus, attaining UNESCO World Heritage status will also leverage important societal values such as the public communication of science.
We will also consider the fate of observatories which are no longer in active use. For instance, in Potsdam the main dome has been transformed into a library, whereas in contrast to Cambridge and Meudon where they are falling into disrepair.
Questions that might be asked include:
- The requirements for an observatory to be considered as Outstanding Astronomical Heritage?
- The requirements needed to consider an observatory as a monument for accreditation for UNESCO Word Heritage?
- What defines a "Classical Observatory" from a cultural viewpoint?
Challenges that are encountered in running Classical Observatories include:
- How to keep historic telescopes working and relevant to audiences?
- What can we learn from historic observatory libraries and archives?
- How can an observatory on the UNESCO World Heritage list proceed with undertaking modern cutting-edge research?
- How do historic observatories manage the balance between visitors' expectations (black holes - wow!)
versus historic reality (transit telescopes and cataloguing - boring!)?
- How might we retain observatory domes once they have stopped being actively used for research?
