"LLANVAIR-TRÊLYGON (LLAN-VAIR-TRÊVHELYGEN), a parish in the hundred of TROEDYRAUR, county of CARDIGAN, SOUTH WALES, 3 1/2 miles (N. E.) from Newcastle -Emlyn, containing 124 inhabitants. This parish,which is situated in the southern part of the county, comprises but a small extent of arable and pasture land, which is in tolerable cultivation. The surrounding scenery is not distinguished by any peculiarity of features; and the adjacent country, though varied in appearance, is neither remarkable for picturesque beauty nor for objects of antiquarian interest, The living is a rectory not in charge, annexed to the vicarage of Llandyvriog, in the archdeaconry of Cardigan, and diocese of St.David's. The church, dedicated to St. Mary, having been suffered to fall into decay for want of due repair, is now in ruins. On the north side of the church, and at no great distance from it, is a circular tumulus surrounded by a moat, which is said to have been formerly used as a place of defence; but nothing is recorded of any event of historical importance with which it was connected. The acerage annual expenditure for the support of the poor is £27.11."
