Climate Change & Coastal Heritage

CHERISH (Climate, Heritage and Environments of Reefs, Islands, and Headlands) is a 6-year European-funded Ireland-Wales project, bringing together four partners across two nations: the Royal Commission on the Ancient and Historical Monuments of Wales, the Discovery Programme: Centre for Archaeology and Innovation Ireland, Aberystwyth University: Department of Geography and Earth Sciences and Geological Survey, Ireland. The project began in January 2017 and will run until June 2023. It will benefit from €4.9 million through the Ireland-Wales 2014-2020 Programme.


CHERISH is a truly cross-disciplinary project aimed at raising awareness and understanding of the past, present and near-future impacts of climate change, storminess, and extreme weather events on the rich cultural heritage of our sea and coast. We link land and sea and employ a variety of techniques and methods to study some of the most iconic coastal locations in Ireland and Wales.

Jo I was lucky enough to join the CHERISH funded dig at Caerfai in 2021. This Iron Age promontory site at Penpleidiau is surrounded by sea on 3 sides and protected on the north with not one but 4 (yes, 4!) rampart and ditch structures. Even though this site may seem protected, climate change and its proximity to the sea is causing it
