From this singular eminence there is a far-stretching view of the valley of the Dee, as the river speeds on its way to a rich and more open country. Near to where the stream is further swollen by receiving the waters of the Ceiriog, it is spanned by the majestic aqueduct which carries the waters of the Ellesmere Canal, one of those few architectural achievements which, placed where Nature has done her utmost, add a new beauty to their surroundings. Even more unrestrained praise might be given to the fine, slender, lofty pillars and arches of the Dee viaduct, which is among the greatest works of the Great Western Railway. The aqueduct is Telford's work, and the viaduct was built by Robertson. For the former, however, Telford claimed no credit, for he wrote thus in praise of his foreman:--"The Vale of Llangollen is very fine, and not the least interesting object in it, I can assure you, is Davidson's famous aqueduct, which is already reckoned among the wonders of Wales." Churchyard differentiates very discreetly and observingly between the Ceiriog and the Dee. The one, he says, is "a wonderous violent water when rayne or snowe is greate," and the other is "a river deep and swifte," running "with gushing streame." The meeting-place of the two rivers is distinguished as the site of two famous houses, each surrounded by fine parks. On one side is the feudal castle of Chirk, and on the other is Wynnstay, which has long been the seat of the great family after which it is named. Chirk Castle dates back to the eleventh century. It was the home of those Myddletons to whom belonged that famous Sir Hugh Myddleton who brought the New River to London. Wynnstay also has its history, for here lived Madoc ap Gruffydd Maelor, who built Valle Crucis Abbey. It is now the principal seat of Sir Watkin Williams Wynn, whose possessions are so extensive that he is sometimes called the real Prince of Wales. The present Hall dates only from a time that is still very recent, for its predecessor was burned down in 1858. From the terrace of Wynnstay there is such a view of the Dee--of wood, of river, of lofty bridge and distant mountains slopes--as seems almost to belong to the landscape of another world.
