We entered TREDEGAR PARK in succession, a very ancient seat of the Morgan family. This park is laid out in the obsolete style of groves and avenues; but possesses great room for modern taste, in the variety of swell and hollow composing its surface, the remarkable size and beauty of the oaks and Spanish chesnuts with which it is decorated, and the picturesque course of the rapid Ebwy, whose red rocky banks form a striking contrast to the surrounding verdure. The turnpike road passes through the park, and within a few hundred yards of the mansion, a huge quadrangular brick building, of the date of Charles the Second’s reign, with a high shelving roof, in which are two or three tiers of windows, similar to the weighing-house at Amsterdam. Internally, the house is convenient and well arranged, with state and domestic apartments, several of which are preserved in their original character. The most remarkable is the oak room; the flooring of which, forty-two feet by twenty-seven, was furnished by a single oak; and the wainscoting, formed of the same material, is much admired for its antique carving. A large collection of pictures, chiefly family portraits, is distributed through the house; but few of them are valuable as specimens of art. Among the extensive offices are several remains of the ancient castellated mansion, described by Leland as “a very fair place of stone.” The Morgan family being one of the most ancient and considerable in Wales, the ingenuity of the bards has been excited to trace its origin: some have venally derived it from Cam the second son of Noah; but others refute this position, and modestly carry it no further than his third son. Without noticing several intervening personages contended to be the founders of this family, Cadivor the great, lord of Dyfed, who died anno 1084, appears to be the only one well supported in the appointment of its great ancestor.
