One of the strongest of these embattled fastnesses was <g>Castell-glyn-y-Striguil</g>,[101] erected, according to Doomsday-book, by the Norman warrior so often named in this work, William Fitzosborne. In Hammer’s Irish Chronicle,[102] however, its erection is ascribed to Gilbert Strongbow, whose life and family we have already noticed in the account of Tinterne Abbey. The remains of this castle, though inadequate to convey any just notion of its original strength, are still sufficiently marked with regard to its size and proportions. Its outworks have mouldered down into shapeless masses, over which nature has thrown so dense a matting of underwood, that the traces of art have been almost obliterated. The form “was that of an oblong square, the angles of which, as usual in such cases, were defended by octagonal towers;”[103] at one extremity was the donjon, or keep, the situation of which is indicated by the shapeless mound of vegetation, which draws nutriment from its débris. The walls were encircled by a deep moat, supplied by two mountain rivulets, which unite at this point to form the <g>Troggy</g>, one of the silver tributaries of the river Usk.
The other castles Avhich deserve a cursory notice, are, Llanvair, Llanvaches, Pencoed, Dinham, and Penhow.[104] The latter, an ancient seat of the <g>Seymours</g>, occupies a bold and romantic situation. The acclivity which forms the direct approach to it, is nearly perpendicular. The view which it commands consists of a valley, or rather wooded ravines, in the foreground; and in the distance, a range of barren hills that bound the horizon--
Hills that, giving birth To circling fountains, glad the parent earth; And from their bosom, framed for martial toil, Sent forth the guardian heroes of the soil.
By the marriage of the Lady Jane, daughter of Sir John Seymour, with Henry the Eighth, and the birth of their son, afterwards Edward the Sixth, the house of Penhow was placed in a situation to compete with that of Raglan; and by the fortuitous influence thus acquired, the Seymours took a leading authority in the management and direction of county affairs.
This castle, or rather fortalice, appears to have derived its strength, more from its isolated and once inaccessible position, than from the extent of its walls or outworks. A portion of the interior has been repaired and rendered habitable, or rather a house has been erected on the site of the old _berçeau_, and thus future patriots and statesmen may yet “come forth of Penhow.”
