Fladda's archaeology is recorded by the Royal Commission on the Ancient and Historical Monuments of Scotland.
It refers to a building and mounds which may be the site of an early Christian chapel and burial ground.
Fladda is mentioned in Frank Fraser Darling's book Island Years.
He lived on the neighbouring island of Lunga with his wife and son while carrying out research.
Darling notes that Fladda was the site of the summer home of the Robertsons, who at that time had been fishing lobsters around the Treshnish Isles for three generations.
