Tourism interests in Kerry have expressed concern over the condition of lightkeeper dwellings on the Blasket island of Inishtearaght or An Tiaracht.
As RTÉ reports, the condition of the houses is deteriorating due to a combination of Atlantic weather and lack of maintenance.
Concrete capping at the landing slip beneath the lighthouse station has also been eroded.
The lighthouse on a 200-metre high rock dates from 1870, and up to 13 people lived in the dwellings. A keeper fell to his death in 1913 when trying to catch a goat for milking.
Lightkeepers were withdrawn when the lighthouse was automated in 1988.
The Blasket islands are part of the State’s new marine park or Páirc na Mara, and the chair of Fondúireacht an Bhlascaoid/ the Blasket Foundation Pádraig Firtéar says the 155-year old buildings should be restored and used for research purposes by scientists.
The Commissioners of Irish Lights, which is responsible for the supervision and management of all of Ireland’s lighthouses, told RTÉ that "the operational footprint being maintained is now significantly smaller” since automation and excludes the dwellings and associated buildings.
“Irish Lights continually reviews the condition of the properties at Inishtearaght and will prioritise work that reduces environmental impact and ultimately aims to promote positive biodiversity on the site which lies within the Blasket Islands Special Area of Conservation and Special Protection Area, and Páirc Náisiúnta na Mara Ciarraí," it said.
Main means of access to An Tiaracht is by helicopter, it pointed out, and the boat landing would only ever be used for emergencies.
"Given the hazardous nature and location of this lighthouse, public access is not permitted."
