"LLANTRITHYD (LLAN-TRYDDYD), a parish in the hundred of DINAS-POWIS, county of GLAMORGAN, SOUTH WALES, 3 miles (E. S. E.) from Cowbridge, containing 221 inhabitants.
On the conquest of Glamorgan by Robert Fitz-Hamon, and its subsequent division, the castle and manor of Llantrithyd were assigned to Hywel ab Iestyn ab Gwrgan, with the privilege of exercising jura regalia therein. The castle was demolished, in 1151, by Meredith, great grandson of Rhys ab Tewdwr.
The village, which stands about a mile to the south of the road between Cardiff and Swansea, occupies a secluded situation in a well-wooded valley, which is watered by a small rivulet. Llantrithyd House, formerly the seat of the Bassets, and subsequently of the Aubreys, is now in ruins : it was a fine specimen of the style that prevailed in the reign of Henry VI., with later additions, and is stated by tradition to have afforded an asylum, during the Commonwealtb, to many great and learned men of the Church of England, by whom academical degrees were here conferred.
On a rising ground above the village is pleasantly situated Tyvree, a cottage ornee, the residence of Henry Seymour, Esq., who is proprietor of a considerable part of the parish, and to whom also belongs an extra-parochial farm of about one hundred and twenty acres, called Caer-main, together with twenty-four acres contiguous, also tithe-free. Limestone abounds in the parish, in which also a considerable quantity of lead-ore is found.
The living is a discharged rectory, in the archdeaconry and diocese of Llandaf, rated in the king's books at £8. 13. 4., and in the patronage of Sir Thomas Aubrey, Bart. The church, dedicated to St. Illtyd, is a respectable edifice, containing a few ancient monuments, among which may be particularly noticed a stately one to the memory of a knight and his lady, of the Basset family, in the best character of the style which prevailed in the reign of Queen Elizabeth. In the churchyard is a remarkable yew tree, which, at the height of six feet from the ground, measures twenty-six feet in girth, and near the root, little less than forty feet.
The ancient hall, wherein the manorial courts were held, still remains, and having been applied, since the abolition of the independent jurisdictions of the lordships marcher, to the reception of the poor, it is now called " the Church House."
Here is a mineral spring, the water of which is said to be efficacious in the cure of fluxes.
The poor of this parish are entitled to the produce of two acres of land in the parish of St. Hilary, purchased with £45, the bequest of an unknown benefactor, and to the interest of £50, bequeathed, in 1744, by Mrs. Lougher. The average annual expenditure for their support is £76. 7."

Llan Thyddyd house, a Seat of Sir John Aubrey's, is a spacious edifice, and presents a fine specimen of Architecture of the reign of King Henry the Sixth; some of the Windows are uncommonly large. In the Chancel of the Church is a grand and superbly ornamented Monument, erected in the early part of the reign of Queen Elizabeth, and on which are the recumbent figures of a Knight and his Lady, as large as life; and connected with it above, are the figures of a Knight and his Lady, nearly as large as life, in the attitude of Prayer.
