we may probably be correct in attributing to the Northmen of the 

 9th and loth centuries. 



I may mention in some support of this theory that without 

 the lake the name Coolsallagh has little present meaning. With 

 the lake restored the rectangular corner of the high lands would 

 at once re-appear. The name Coolsallagh, the corner of the Sallys, 

 from its simplicity cannot be as old as the original lake, 

 2,500 )'ears or so old, it can only be derived from a "corner" of, 

 in comparison, more or less recent years. 



The Mount of Dromore is very remarkable, as it seems to be 

 a clear example of a Norman moat built right on the top of an 

 ordinary Danish ring fort, a typical Norman square bailey or keep 

 being added on the south side. If Mr. Goddart Orpen is correct, 

 as he certainly seems to be, in identifying Dromore Mount as the 

 Castle of Maghcobha, or Moy Cove, we can tell something of its 

 history. It was occupied by John de Courcy in 1188. In 1252 

 the English Justiciar John Fitz Geoffrey, in his expedition against 

 Bryan O'Neill, rebuilt and strengthened the Castle of " Maicove," 

 so that we may probably be correct in dating the moat and bailey 

 of Dromore, 1252, and the ring fort upon which they are piled 

 to the 9th century, the work of the Northmen invaders.
