Why are we working here?
Coastal erosion has had a very noticeable impact upon Porth y Rhaw which has shaped the site over thousands of years. CHERISH is working at the site both to provide objective 3D data for erosion monitoring and to further understand the threated archaeology of the site. Detailed archaeological research has highlighted that visible erosion is by no means a modern phenomenon, with the builders respecting the huge eroded central chasm by building the defences around it. Previous interpretations suggested that the chasm had largely formed after the site was constructed.
