The mansion is a noble pile of building, of fine white stone, and has, recently, under the direction of the present possessor of Wynnstay, undergone much improvement. The interior comprises several noble apartments, which are embellished with paintings by the first masters, portraits of various members of the family, and busts by eminent sculptors, of the distinguished statesmen Lord Grenville, William Pitt, &c. The library consists of a fine collection of books, in ancient and modern literature, with valuable MSS. illustrative of early British history. Among the variety of plate, including elegant race-cups, &c., is a large silver vase, or punch-bowl, presented to the late Sir W. W. Wynn, by his countrymen, on his return from the battle of Waterloo. The grounds in which the house is situated are remarkable for their sylvan beauty. The avenue leading to the mansion from Rhuabon is formed of fine oak, elm, beech, and other trees, one of which, “The King,” measuring thirty feet in circumference, and with its outspreading arms appearing to bid defiance to its fellows, seems to have a just claim to the monarchical title it bears. A fine sheet of water in front of the house adds much to the picturesque and deeply-wooded scenery around. Both the near and distant views from the park are distinct and attractive, those especially towards the Berwyn chain of mountains, with the grand breach in it beyond Llangollen, through which rolls the rapid Dee. An obelisk or handsome free-stone column is erected in the park, after a design by Wyatt, as a tribute of maternal affection, in memory of Sir Watkin Williams Wynn, grandfather of the present baronet. Round the entablature is a gallery, with a circular iron balustrade, nine feet high, in the centre of which stands a handsome urn in bronze. The plinth is wreathed with oak leaves descending from the beaks of eagles. A door-way leads, by a wide stair-case, to a gallery at the top. On the lower part of the Cenotaph is the following emphatic inscription:— “FILIO OPTIMO. MATER CHEU! SUPERSTES.” Although this column cannot be seen from the house, a glimpse of it may be caught on the left side of the railway, in passing from Rhuabon towards Oswestry. The Nant-y-Bela Tower, in “The Dingle of the Marten,” is another Cenotaph, erected by the late Sir W. W. Wynn, after a design by Sir Jeffrey Wyattville, in memory of his brother officers and private soldiers slain in Ireland during the rebellion of 1798. It stands on an eminence, and commands a view of the Vale of Llangollen, for several miles. The Waterloo Tower, close also to the railway, is another ornament to the park.
