Dun EOCIIL.V. (O.S. 110.) 

 Dun Eochla, or, as is usual with English siieakers, Dun Ogliil, is the most 

 prominent fort in the island after Dun Aengusa, indeed more so than the latter, 

 so far as those landing at Kilrouan are concerned. It stands on the brow of 

 the central hill, not on the actual summit, but on the edge, perhaps for some 

 siielter from the fierce westerly gales. The name is lost, for O'Donovan's 

 Dun Kimbi or Dun Tamain is a play of imagination, and those cliiefs were 

 connected not witli Aranmore but with Lougli Hackett and Tawin Island. It 

 forms one of a line of four stone ring- walls, which, with many stone huts, 

 formed an extensive early settlement at Baile na Sean.

The Dun is a fine double enclosure, and is seen at its best from the 



' John OFlahcrly, Trans. K. I. Acad. xiv. (Antiq.), p. 133, and 0. S. Lcllere, Ogbil. There is 

 probably an allusion in CaeiUe's song to russet oaks in Aran (Silva Gadelica, ii., p. 109;.
