The crannog of _Mac Navin_,[163] county Galway, was taken in the year 1610; it is previously mentioned under date 1601. G. H. Kinahan, who searched for but could find no trace of this crannog, imagined its site must have been somewhere in the large alluvial flat and bog that extends south of the townland of Crannagh, in the parish of Tynagh, county Galway. This supposed site lies about four miles E.N.E. of the crannog of Ballinlough. The difficulty experienced in identifying the site is the more remarkable as the descendants of the sept of Mac Navin still reside in the locality, and the crannog was inhabited up to a very late period.[164] In 1603, after the subjugation of Leitrim by the Crown, “O’Rourke was obliged to remain with a small force in the woods, in the remote glens and on the islands in the lakes in his country;” whilst the same year Hugh Boy O’Donnell was conveyed by his adherents to the retirement of a crannog, to be healed of his wounds. This retreat, called “_Crannog-na-n-Duini_, in Ross Guill, in the Tuathas,” was situated in the parish of Mevagh, county Donegal, between Redhaven and Sheephaven. In 1599 the crannog of _Lough Gur_, county Limerick, was taken from the “Queen’s people” by the Earl of Desmond, then in rebellion against Elizabeth. Sir George Carew relates that the Lord President of Munster, who reconnoitred the crannog for the purpose of its recapture in the following year, _i.e._ 1600, observed two small islets (the crannogs) and one large island; this latter “he found to be a place of exceeding strength, by reason that it was an island encompassed with a deep lough, the breadth thereof being, in the narrowest place, a caliver’s shot over. Upon one side thereof standeth a very strong castle, which at this time was manned with a good garrison, for there was within the island John Fitz Thomas with two hundred men at the least.”[165] “After much parade in the preparation of ordnance to reduce Lough Gur, its surrender was purchased for sixty pounds from Owen Grome, who had been entrusted with its defence.”[166] There yet lingers here “the reflex of a legend past,” for it is supposed that beneath the waters of the lake lie enchanted the grand old castle of the Desmonds, the great earl himself, his beautiful countess, and all the retinue that surrounded him in the days of his splendour. “In one of the lakes is a small island, rocky and wooded, which is believed by the peasantry to represent the top of the highest tower of the castle, which sank under a spell to the bottom.”[167]
