ESO News: Launch of UNESCO–IAU Astronomical Heritage Web Portal

Buildings and monuments relating to astronomy throughout the ages stand as a tribute to the diverse and often complex ways in which people have rationalised the cosmos and framed their actions in accordance with their understanding of it. This includes, but is by no means restricted to, the development of modern science.

The importance of the sky in human heritage was recognised by UNESCO when it established its Astronomy and World Heritage Initiative in 2003, and in 2008 it signed a Memorandum of Understanding with the IAU. Since then, the two organisations have been working together to promote astronomical sites of potential “Outstanding Universal Value”.

The online portal is the latest and potentially most significant deliverable from the accord set up between UNESCO and the IAU four years ago, and results directly from a collaboration between the IAU’s Astronomy and World Heritage Working Group (AWHWG) and the Ancient Skies Project set up through the IYA2009 Astronomy and World Heritage Cornerstone Project. Professor Clive Ruggles, Emeritus Professor of Archaeoastronomy at the University of Leicester, UK, is Chair of the AWHWG. He said: “A lot of our most precious astronomical heritage — both ancient and modern — is under threat. If we don’t act to try to protect and preserve it, we run the risk of losing it. Over the coming months and years this web portal will become ‘the’ vehicle for actively supporting, as well as sustaining, political and public interest in the promotion and protection of astronomical heritage sites, both cultural and natural.”

A previous AWHWG milestone was the Thematic Study on Astronomical Heritage produced in 2010 by the IAU, working together with ICOMOS, UNESCO’s advisory body for cultural sites. Endorsed by UNESCO’s World Heritage Committee in 2010, the Thematic Study provides guidelines for UNESCO member states on the inscription of astronomical properties. Much of its content has been incorporated onto the portal.

The portal contains:

• a range of general information pages;
• thematic essays and case studies, searchable geographically and temporally using a specially developed “heritage finder” tool; and
• a discussion forum permitting authorised users to discuss current entries, propose additions and changes, propose new heritage entities (case studies), and discuss general issues.

The portal will not only feature sites and monuments, but also other types of astronomical heritage such as portable instruments and intangible cultural practices, as well as dark-sky places.
