Caernarvon is the largest of Edward’s castles, and is probably still the most entire; the river Seiont and the Mænai strait washed the walls on two sides, and a deep fosse, originally crossed by a drawbridge, completed the watery circuit. The entrance possesses an air of much grandeur. It is a lofty pointed arch, defended by noble flanking towers, and adorned with a colossal figure of the conqueror himself, standing in a canopied niche, in the act of unsheathing his sword. The interior, which is represented in the accompanying view, is much more ruined. The apartments for the accommodation of the garrison are quite buried in rubbish. Of the entrance gates, a fine ribbed archway, with the grooves of four successive portcullises, are still distinct; the mural gallery is complete nearly round the whole circuit of the castle, and the outer walls of the royal apartments, with the enriched mullions of the windows, yet unbroken. From the walls of the great western towers, light delicate turrets, of polygonal forms, appear to spring; one of these is accessible by stone stairs to the summit, which is adorned with the figure of an eagle, said to have been brought hither from Segontium by the Saxon king, but more probably a species of ornament suggested to the founder by the proximity of the Roman citadel, and intended to be complimentary to the inhabitants. From the observatory, on the top of the eagle tower, there is an extensive prospect over the Island of Anglesea, the Bay of Caernarvon, and the low lands along the base of the mountains, but it is wholly commanded by the hills on either side of the town. The graceful archway, called Queen Eleanor’s gate, does not appear to have been a portal of entrance. From this a platform may have been lowered, on which the queen mother appeared holding forth her royal infant towards the assembled chieftains, and, after the performance of this great mockery, restored to its secure fastenings in the wall; but no satisfactory evidence appears of any entrance doors, except the chief one mentioned previously, and the water-gate at the western end of the castle. The Newborough, Bulkeley, and Mostyn families have successively been vested with the government of the town and constableship of the castle, cares now entrusted to the Marquis of Anglesea. The town walls are still perfect, and interesting to the antiquary. A handsome assembly room has been fitted up within the towers of the principal gate, at the expense of Sir Watkyn W. Wynne, Bart. An elegant chapel of ease occupies the northern angle of the walls, and includes one of the large rounders; and a beautiful barbacan, in advance of the water-gate, is in the most entire preservation. Caernarvon is situated in the parish of Llanbeblig, and the parish church, an ancient edifice, dedicated to Saint Publicius, stands at the distance of about one mile from the castle.
