The third 100 IUGS Geological Heritage Sites

The International Union of Geological Sciences (IUGS) has announced the Third 100 IUGS Geological Heritage Sites, recognising places of outstanding scientific importance for understanding Earth and its history.

Announced during the IUGS Geoheritage Event 2026 in Portugal, the new selection brings the total number of recognised sites to 300, following the First 100 announced in 2022 and the Second 100 in 2024.

The Third 100 includes sites across 47 countries, as well as sites in Antarctica and on the high seas. Together, they represent a remarkable diversity of geological features, processes and discoveries.

The recognition of these sites helps raise awareness of their scientific and educational value and supports efforts to conserve geological heritage for future generations.
