Hosty was not long in the quiet possession of this Castle when Bermingham came hither from the north, where he was after gaining a great victory, and drove him out of it partly by force and partly by treachery ; and his descendants who assumed the name of Mac-orish, maintained possession of it until the wars of Ireland, when Col. Hoath drove them out. This is all that tradition remembers of this fortress. The Castle stands on a small hill over a rivulet about a quarter mile to the west of the little town of Dunmore. The hill seems to have been originally crowned with an earthen 'Dun', from which the name, but it is now so effaced that no idea can be drawn as to the extent or character. The entire hill was enclosed by a strong wall now almost entirely destroyed, some of it scattered about in massy fragments, and some tumbled in the rivulet. The Castle itself is a square building, measuring on the inside 45 feet in length and 27 in breadth, and, as well as I could judge by the eye, 60 in height. Walls 7 ft. thick. It had three lofts, as appears from the windows and the holes for joists. It certainly does not appear to be the fabric erected by Hosty-Mac-Membric. The Four Masters have collected the following Annals of this place, from which it appears that it was an ancient Irish Military station before the arrival of the Anglo-Norman and Welsh families. "1133, Cormac MacCarthy and Conor O'Brien led an army into Connaught and killed Cathal O'Conor Raydamna of Connaught and O'Flynn, chief of Sil-moc-lomain, and the DEMOLISHED Dunmugdorn and DUN-MORE, and plundered a great part of the country." "1143, Morogh O'Melaghlin, King of Meath, was most treacherously taken prisoner by King Turlogh O'Conor, and confined with other Meathian prisoners in DUN-MORE." "1159, Murtagh MacLoughlin (presumptive monarch of Ireland) with the nobles of Kinel-Connell, Kinel-Owen and Oriel, marched an army into Connaught and burned Dun-More, Dun-Ciar and Dun na ngall and devastated a great part of the country." These three notes are antecedent to the period of Hosty Mac Membric. The following are subsequent to it: "1249, Dunmore was burned by he sons of the King of Connaught." "1271, Matthew O'Conor was killed by the English of Dunmore." "1284, Dunmore was burned by Fiachra O'Flynn." "1569, Sir Henry Sydney took (the Castle of) Dunmore Mac-Feorais and Roscommon." Archdall is wrong in making this the 'Domhnach padraig' of the Tripartite, as we shall show when treating the parish of Donagh-patrick. It is sufficient here to observe that the two names are not identical, and that DUN-more is not a corruption of DOMHNACH-more as Donshaughlin in Meath of Domhnach Seachlainn. *It is possible that it could be a corruption of it,* but, we know from history that it is not. We therefore come to the historical conclusion that there was no abbey at Dun-mor in Cor-maicne Kinel-Dubhain until the year 1425, when Walter de Birmingham, Lord Baron of Athenry, erected there a friary for Augustinian Eremites. The remains of this house are in the same state as described by the French artists in 1779: "This Abbey is in the town of Dunmore, and, I believe, was much larger, but cannot be traced as the ground is level and no ruins about, it being a kind of market, the part A. on the plan is a waste, the arches built up, and B. is converted into a parish church where service is performed. Over the door C. are arms and an inscription which I copied. Said to be built by the Lords of "Athenry". More to come.............
