THE IRISH PENNY JOURNAL. NUMBER 4. SATURDAY, JULY 25, 1840. VOLUME 1. [Illustration: CAISLEAN-NA-CIRCE, OR THE HEN'S CASTLE.] Our prefixed illustration gives a near view of one of the most interesting ruins now remaining in the romantic region of Connemara, or the Irish Highlands, and which is no less remarkable for its great antiquity than for the singularly wild and picturesque character of its situation, and that of its surrounding scenery. It is the feature that gives poetic interest to the most beautiful portion of Lough Corrib--its upper extremity--where a portion of the lake, about three miles in length, is apparently surrounded and shut in by the rocky and precipitous mountains of Connemara and the Joyce country, which it reflects upon its surface, without any object to break their shadows, or excite a feeling of human interest, but the one little lonely Island-Castle of the Hen. That an object thus situated--having no accompaniments around but those in keeping with it--should, in the fanciful traditions of an imaginative people, be deemed to have had a supernatural origin, is only what might have been naturally expected; and such, indeed, is the popular belief. If we inquire of the peasantry its origin, or the origin of its name, the ready answer is given, that it was built by enchantment in one night by a cock and a hen grouse, who had been an Irish prince and princess! There is, indeed, among some of the people of the district a dim tradition of its having been erected as a fastness by an O'Conor, King of Connaught, and some venture to conjecture that this king was no other than the unfortunate Roderick, the last King of Ireland; and that the castle was intended by him to serve as a place of refuge and safety, to which he could retire by boat, if necessity required, from the neighbouring monastery of Cong, in which he spent the last few years of his life: and it is only by this supposition that they can account for the circumstance of a castle being erected by the O'Conors in the very heart of a district which they believe to have been in the possession of the O'Flahertys from time immemorial. But this conjecture is wholly erroneous, and the true founders and age of this castle are to be found in our authentic but as yet unpublished Annals, from which it appears certain that the Hen's Castle was one of several fortresses erected, with the assistance of Richard de Burgo, Lord of Connaught, and Lord Justice of Ireland, by the sons of Roderick, the last monarch of the kingdom. It is stated in the Annals of Connaught, and in the Annals of the Four Masters, at the year 1225, that Hugh O'Conor (son of Cathal Crovedearg), King of Connaught, and the Lord Justice of Ireland, Richard De Burgo, arriving with their English at the Port of Inis Creamha, on the east side of Lough Corrib, caused Hugh O'Flaherty, the Lord of West Connaught, to surrender the island of Inis Creamha, Oilen-na-Circe, or the Hen's
