LLANGWYRYVON, or LLANGRWYDDON (LLAN-Y-GWYRYFON), a parish, in the union of ABERYSTWITH, lower division of the hundred of ILAR, county of CARDIGAN, SOUTH WALES, 8 miles (S. by E.) from Aberystwith; containing 642 inhabitants. The name of this place signifies "the church of the Virgins," and is derived from the dedication of its church to St. Ursula and the eleven thousand virgins. The parish is situated on the southern bank of the Wyrai river, and comprises a considerable tract of inclosed and well-cultivated land, with a lair portion of open and elevated common. The soil is generally fertile, and in some places argillaceous: turbaries are found in various places, and some of the higher grounds are abundantly productive of oorn and hay. The living is a perpetual curacy, endowed with £800 royal bounty, and £1200 parliamentary grant; net income, £176; patron and impropnator, J. P. B. Chichester, Esq. The church, situated on an eminence, is a small ancient edifice, consisting only of a nave and chancel, formerly divided by a curiously carved screen. In the churchyard is an old monumental stone, highly ornamented, and having the figure of a cross sculptured upon it, but without any inscription; it is now used as a gate-post. Owing to the elevated situation of the church, the cemetery commands a fine view of the river and the surrounding country. There are places of worship for Calvinistic and Wesleyan Methodists, in the former of which two schools are held, where the entire congregations assist in instructing each other in reading the Scriptures, and other exercises; and there is a day school, in which 40 children are taught at the expense of their parents. Within the limits of the parish are the remains of an intrenchment, of a curvilinear form; but nothing is known either of its origin or history.
