These iconic Irish landmarks now join other globally significant sites, such as Mount Vesuvius, Yosemite Valley, and the Dead Sea, as part of the IUGS Geological Heritage Sites.

The site, recognized for the “Carboniferous evolution of The Burren and Cliffs of Moher,” was included in the Second 100 IUGS Geological Heritage Sites during the 37th International Geological Congress in Busan, South Korea.

The selection process involved contributions from over 700 experts representing 80 countries and 16 international organizations, officially recognizing the best examples of geological features worldwide.

The inclusion of this Co. Clare geological site follows its nomination by Dr. Eamon Doyle, Geologist at the Burren and Cliffs of Moher UNESCO Global Geopark. According to Doyle, the site’s selection is due to its exceptional representation of Mississippian limestones in unique karst landscapes and Pennsylvanian deltaics visible in the dramatic sea cliffs.

“This is a tremendous honor for the Geopark and for all those passionate about Irish geology, especially as the Burren and Cliffs of Moher is only the second site from the island of Ireland to be recognized in the two Top 100 lists, following the inclusion of Giant’s Causeway in Co. Antrim in the First 100 in 2022,” Doyle noted.

He added, “The Burren is an extraordinary limestone region with a unique combination of geology, flora, caves, archaeology, history, and farming traditions, making it a place of both beauty and mystery. This new designation will enhance awareness and appreciation of the area’s ancient geological history, spanning from its formation to the retreat of the ice sheets 12,000 years ago, and its continued evolution.”

Doyle also acknowledged the support of Geological Survey Ireland (GSI) and Professor Patrick Wyse Jackson of Trinity College Dublin, the IUGS representative in Ireland, for their assistance in the application process.

Koen Verbruggen, Director of GSI, Department of Environment, Climate and Communications, emphasized that the Second 100 IUGS Geological Heritage Sites, like the First 100, are recognized for their “high scientific value.”

“These sites represent the best examples of geological features and processes, offering remarkable insights into Earth’s history and the development of geology as a science,” Verbruggen said. “The recognition of the Burren and Cliffs of Moher will further elevate the site’s value as an educational resource and promote its preservation.”
