Let us now journey westward from the Dee into Wales, coming first into Flintshire. The town of Flint, it is conjectured, was originally a Roman camp, from the design and the antiquities found there. Edward I., six hundred years ago, built Flint Castle upon an isolated rock in a marsh near the river, and after a checquered history it was dismantled in the seventeenth century. From the railway between Chester and Holyhead the ruins of this castle are visible on its low freestone rock; it is a square, with round towers at three of the corners, and a massive keep at the other, formed like a double tower and detached from the main castle. This was the "dolorous castle" into which Richard II. was inveigled at the beginning of his imprisonment, which ended with abdication, and finally his death at Pomfret. The story is told that Richard had a fine greyhound at Flint Castle that often caressed him, but when the Duke of Lancaster came there the greyhound suddenly left Richard and caressed the duke, who, not knowing the dog, asked Richard what it meant. "Cousin," replied the king, "it means a great deal for you and very little for me. I understand by it that this greyhound pays his court to you as King of England, which you will surely be, and I shall be deposed, for the natural instinct of the dog shows it to him; keep him, therefore, by your side." Lancaster treasured this, and paid attention to the dog, which would nevermore follow Richard, but kept by the side of the Duke of Lancaster, "as was witnessed," says the chronicler Froissart, "by thirty thousand men." Rhuddlan Castle, also in Flintshire, is a red sandstone ruin of striking appearance, standing on the Clwyd River. When it was founded no one knows accurately, but it was rebuilt seven hundred years ago, and was dismantled, like many other Welsh castles, in 1646. It was at Rhuddlan that Edward I. promised the Welsh "a native prince who never spoke a word of English, and whose life and conversation no man could impugn;" and this promise he fulfilled to the letter by naming as the first English Prince of Wales his infant son, then just born at Caernarvon Castle. Six massive towers flank the walls of this famous castle, and are in tolerably fair preservation. Not far to the southward is the eminence known by the Welsh as "Yr-Wyddgrug," or "a lofty hill," and which the English call Mold. On this hill was a castle of which little remains now but tracings of the ditches, larches and other trees peacefully growing on the site of the ancient stronghold. Off toward Wrexham are the ruins of another castle, known as Caergwrle, or "the camp of the giant legion." This was of Welsh origin, and commanded the entrance to the Vale of Alen; the English called it Hope Castle.
