"The tower that long had stood The crash of thunder and the warring winds. Shook by the slow but sure destroyer--Time, Now hangs in doubtful ruins o'er its base." Harlech Castle, according to the Welsh historians, derives its origin from Maelgwyn Gwynedd, prince of North Wales, who flourished at the commencement of the sixth century. The present castle appears to have been rebuilt by Edward I., on the foundations of the original fortress, portions of which are still observable in the masonry of the latter epoch, so well known as the "castle-building reign" in England. In the reign of Henry IV. the castle was seized by Owen Glendower, but was retaken four years later; and, after the battle of Northampton, in 1460, afforded temporary shelter to Margaret of Anjou. In 1468, the castle of Harlech was captured, after a short siege, by the Earl of Pembroke; of whom Sir John Wynne, in his history of the Gwydir family, quotes some Cambrian lines expressive of the ravages committed by him in the counties of Merioneth and Denbigh at that unhappy period. The last of the many tempestuous scenes with which this fortress has been visited occurred in 1647, when William Owen, with a garrison of only twenty men, surrendered it to Cromwell's forces under General Mytton; but this was not accomplished till every other castle in Wales had deserted the royal cause. This castle is a strong square building, with a round-tower at each angle, and one of the same form at each side of the gateway. Besides these there are four other turrets, smaller and higher, which rise above the towers at the angles, and are in a more dilapidated state. The entrance is under a pointed arch, which formerly contained six gates of massive strength and construction. Although the roofs, doors, and casements of this interesting stronghold have long disappeared, it still presents in the distance an air of even habitable preservation. There are the remains of stone staircases in every tower, and in the area one of these, leading to the top of the battlements, is still entire. In all the rooms fire-places, with pointed arches, are visible, as well as window recesses, which in the state apartments are three in a row, and of spacious dimensions; while those in the smaller rooms gradually contract outwards till they terminate in a "slit" or loophole, as in most other castles of this style and period. The view of Harlech Castle is among the finest in this picturesque and interesting country; the situation is commanding, and the effect of these venerable towers and battlements, as they first burst upon the traveller's eye, is strikingly bold and impressive. His fancy is hurried back to the days of other times: the shades of native harpers and native heroes flit before his eye; history and romance divide the empire of his mind; and for a time he rests with mute but intense interest on these castellated landmarks of Cambrian history.
