World Heritage Aspirations

Ireland has three historic observatories that possess a remarkable astronomical heritage, one that stretches all the way back to the Georgian era.  These are the observatories of Armagh, Birr and Dunsink. All three remain active today, places where frontline science continues to be carried out while also serving as centres for communicating science to the public and explaining it to students.  Their heritage is entwined with the telescopes they possess, pioneering instruments of their time that are still found largely in situ today, in how these telescopes were used, and in the science that was carried out there.  The heritage is so strong and so worthy of greater protection that these three Irish observatories have come together to seek UNESCO world heritage listing. 

World Heritage is a designation provided by UNESCO – the United Nations Educational, Scientific and Cultural Organisation – for places that have outstanding universal value to humanity and are worthy of protection so that they can be appreciated and enjoyed by future generations. 

DIAS Dunsink Observatory, on the edge of Dublin, is the oldest of these three, established in 1785 by the Provost of Trinity College Dublin, Francis Andrews.  It now forms a part of the School of Cosmic Physics in the Dublin Institute for Advanced Studies (DIAS).

Armagh Observatory followed in 1790, with a bequest from Archbishop Richard Robinson, the Primate of All Ireland for the Church of Ireland, together with an Act of Parliament he arranged for, to found “an observatory and museum in Armagh for ever”.  The Observatory has operated continuously ever since, now part of the Armagh Observatory and Planetarium.

Birr, in contrast, began as the private observatory of the 3rd Earl of Rosse, set in the grounds of his castle.  It is most famous for the Leviathan he built in 1845, then the largest telescope in the world.  Today, Birr also hosts one of the sites of the LOFAR radio telescope that is distributed across Europe.

Armagh, Birr, and Dunsink observatories represent a living history, places of science running from their foundation to the present day and, hopefully, well into the future.  As such they also display a deep astronomical heritage. We need to protect this heritage, to conserve and preserve their telescopes, instruments and archives, as well as to educate on the importance of science for society and to inspire the next generation. The observatories have now embarked on a journey to seek World Heritage designation to help achieve this objective.
