The Director of the Yeats International Summer School has described the crumbling condition of a childhood holiday home that inspired WB Yeats and his brother Jack as a scandal.
According to Irish Times the lodge was the subject of two planning applications in 2004 and 2005.
Both were granted, subject to several conditions and since expired.
WB Yeats had stayed in Elsinore, which overlooks Oyster Island, in Rosses Point , frequently as a child and as a young man wrote part of The Celtic Twilight there.
The building is on Sligo County Council's list of protected structures.
