I understand that the main threat to the site in question, which is not a national monument in State care, is coastal erosion.
Overall policy for coastal protection, including coastal flooding and erosion, is a matter for the Office of Public Works, while the identification and addressing of coastal protection measures in any particular area is a matter in the first instance for the relevant local authority concerned. My Department has been in contact with the relevant local authority in relation to this site and would be available to offer advice should any proposals for protection works be brought forward.
