LLANVIHANGEL-ABERBYTHIC (LLAN-FIHANGEL-ABER-BYTHYCH), a parish, in the union of LLANDILO-VAWR, hundred of ISCENNEN, county of CARMARTHEN, SOUTH WALES, a} miles (W. S. W.) from Llandilo;. containing 948 inhabitants. This parish derives its distinguishing appellation from its situation at the mouth of the small rivulet Bythic, which here falls into the river Towy; it is within the lordship of Kid welly, and forms part of the Duchy of Lancaster. The environs comprehend many fine views, and much of the varied and interesting scenery that characterises the Vale of Carmarthen. The neighbourhood abounds with limestone, which rises from the sea near Kidwelly, and extends to this parish, and is burned in great abundance for manure, which is conveyed to various parts of the principality. For this purpose a rail-road has been constructed from the works at Castell-y-Garreg, in the parish, to the Burry river, a distance of sixteen miles, crossing the Gwendraeth-Vawr river, and supported near Mynydd Mawr by a strong embankment, containing more than forty thousand cubic yards of earth, which have been thrown up for that purpose. The living is a perpetual curacy, endowed with £200 private benefaction, £400 royal bounty, and £800 parliamentary grant; net income £72; patron, and impropriator, Earl Cawdor, whose tithes have been commuted for a rent-charge of £207. 10. The church, dedicated to St. Michael, a small neat edifice, was, according to a tablet recording the event, erected in 1617, by Sir John Vaughan, Knt., Comptroller of the Household to Charles I.; it was repaired in 1753, by his descendant, the Hon. John Vaughan, representative in parliament for the county. There are places of worship for Independents and Calvinistic Methodists. A neat school-room was built at the expense of the late Lord Cawdor, who paid £20 annually to a master for instructing poor children of the parish, and the same payment is now continued by the present Earl. There are also three other day schools, in which about 60 boys and 50 girls are taught at the expense of their parents; and three Sunday schools, appertaining to dissenters and conducted gratuitously, in which are about 190 males and females. Golden Grove, the ancient seat of the Vaughans, Earls of Carberry, and now the property of Earl Cawdor, is situated within the parish. During the interregnum Cromwell, on his route to besiege Pembroke Castle, abruptly crossed the country, and came to Golden drove with a troop of horse, hoping to surprise Richard, Earl of Carberry, who was zealously attached to the royal cause, and to seize his person; but the earl, having been apprised of his approach, hastily withdrew and hid himself in a farmhouse in a sequestered spot among the hills; and the Protector, disappointed in his intention, concealed his purpose, and, having dined with the countess, continued his route to Pembroke. The old mansion has been recently taken down by the present Earl Cawdor, who has erected, in a more commanding situation, a magnificent structure of the black marble found in the Vale of Llangendeirn, and in the ancient style of English architecture: it consists of a projecting front, having a lofty tower at the south-western angle, with a wing declining a little from the parallel, and containing an extensive range of offices on one side, corresponding to which, on the other, it is said to be his lordship's intention to erect a similar wing, to complete the design. The principal entrance is in the opposite front, under a lofty and elegant porch of three finely pointed arches, through which the carriage drives directly up to the door. The internal arrangements have been designed more with a view to domestic accommodation than to ostentatious display; but they comprehend, an a very liberal scale, all the elegances and decorations suited to the elevated rank of the noble proprietor. The grounds are rather extensive than beautiful, but are well covered with thriving plantations; and from the mansion an almost boundless prospect is obtained, embracing the whole of the beautiful vale from Carmarthen to Llandovery. Among the numerous in. teresting objects which are visible from this spot are Dryslwyn Castle, Grongar Hill, and the venerable ruins of Dynevor Castle, the ancient seat of the native princes of South Wales: the modern mansion of that name is not within view, but the unrivalled and luxuriant scenery of Newton Park is eminently conspicuous. The celebrated Jeremy Taylor, D. D., chaplain to Charles I., and subsequently Bishop of Down and Connor, in Ireland, passed several years during the usurpation at Golden Grove, under the protection of the loyal Earl of Carberry, to whom several of his works are dedicated. 'Within the parish are the remains of a British camp, in a state of tolerable perfection; and in the limestone rock, from which the neighbourhood is supplied with lime for manure, is an extensive cavern, in which bones have been discovered; tumuli of loose stones are of very frequent occurrence in the vicinity, and there is one of these relics of the ancient Britons within the parish.
