The park of Wynstay is well stocked with red deer; excellent plantations; and the house is an elegant modern structure, but nothing in the inside particularly deserving the attention of the traveller. In the grounds, the chief object, worthy of inspection, is a very elegant obelisk, now erecting to the memory of the present Sir Watkin’s father. The height is an hundred and one feet; the base of it sixteen, and the top nine, built with free-stone, and fluted: round the top is formed a gallery, with a handsome urn in bronze, after an elegant design, cast in London; round the base of the column, are wreaths of oak leaves, in the beaks of four eagles, cast in the same metal. On the south-west side is a door, with a stair-case within the obelisk leading to the top: we regretted that the key could not be procured, as the prospect from that eminence must be extremely fine. On the other three sides, an appropriate inscription, in English, Welch, and Latin, is to be carved. Through this park runs Offa’s Dyke, thrown up by the great King of Mercia, from whence it derives its name, to check the irruptions of the Welch, mark the confines of each country, and give greater security to his own. It begins at Basingwerk, in Flintshire, and ends at Chepstow, in Monmouthshire; extending a line of not less than one hundred and fifty miles, over rocks and mountains. This great undertaking still retains the ancient name of _Clawdh Offa_, or Offa’s Dyke. Passing through the little village of Ruabon, situated at the extremity of Sir Watkin’s Park, a very interesting and picturesque country, composed of rich vallies, and gently sloping hills, presented itself to our view; and, at some distance, we soon caught a glimpse of Chirk Castle, a noble seat of the family of the Myddleton’s, standing on an eminence. Four miles from Llangollen, we enquired for the wonderful PONTCYSYLLTY, {147} (pronounced _Pont y Casulte_) or famous aqueduct, now erecting over the river Dee, and found ourselves within half a mile of this great and astonishing undertaking. It is not yet finished; eleven pillars are already completed, built of sandy stone, which is dug on the spot; they are fifteen yards asunder, and their height, from the bed of the river, one hundred and twenty feet: over the whole is to run an iron trough, sufficiently deep for barges of considerable burthen. On the middle column is the following inscription:
