Immediately adjoining the north-eastern extremity of the principal street, the noble demesne of Mr. Pennant originates, and spreads over a wooded surface of considerable area. His castle occupies the site of a palace, erected in the year 720, by Roderic Moelwynog, the last British Prince of Wales, who flourished in the eighth century. The ancient palace was destroyed by Meredydd ap Owain in the year 728, and not rebuilt until some time in the reign of Henry the Sixth, when Gwillim ap Gryffydd raised a stately castle here. This last building endured for many years, and was ultimately subjected to renovation by the hand of a Wyatt; but even this judicious restoration was unable to render it suitable to the rapidly accumulating wealth which the hills of Dolawen poured out upon the board of their fortunate possessor. From a noble design of Mr. Hopper, in a bold and pure Saxon style, a castle has been erected on the ancient site. The style is uncommon, rarely introduced in domestic architecture, and applicable only where the scale is great and the means ample. In this instance the materials, a beautiful dark marble, contribute much to increase the dignity and grandeur of the design, upon which probably one hundred thousand pounds have already been expended. A fine specimen of the Hirlâs, or ancient British drinking horn, bearing the initials of Piers Gryfydd, graven upon the silver mounting, is preserved in the castle of Penrhyn. The castle of Bangor is not to be confounded with that of Penrhyn just described. It was founded some time in the reign of William Rufus, by Hugh, Earl of Chester, but, little of its history survives, and even the ground plan now is with difficulty traced. The process of quarrying, dressing, and preparing slates for public market, and the fanciful titles by which the various sizes are now uniformly designated, are very happily, playfully, and truly described in the following irregular verses. They are the production of the late Mr. Leycester, who was for many years a judge on the North Wales circuit, while the old system of judicature was tolerated.
