TRAWSVYNYDD (TRAWS-VYNYDD), a parish in the hundred of ARDUDWY, county of MERIONETH, NORTH WALES, 12 miles (N. by W.) from Dolgelley, containing 1450 inhabitants. This parish, the village of which is situated on an eminence in an exposed and open mountainous district, on the turnpike road from Tan y bwlch to Dolgelley, is more than ten miles in length and eight in breadth, and more than one-half, consisting of barren hills, is uncultivated, affording only scanty pasturage for sheep and young cattle. The surrounding country is strikingly varied, presenting in some parts the dreary wildness of rugged mountain scenery, in others the softer features of rural beauty, combined with objects of picturesque and romantic grandeur. The lake called Llyn Rathlyn is a fine sheet of water, noted for a peculiar species of perch, having the lower extremity of the back bone strangely distorted: the interesting waterfalls of Pistyll Cain and Pistyll Mawddach, in this parish, have been described in the article on DOLGELLEY. Fairs, which are in general well attended, are held here on April 23rd and September 29th, for horses, cattle; and pedlery; and at Penystryd, in this parish, others are held on August 17th and September 21st. The living is a discharged rectory, in the archdeaconry of Merioneth, and diocese of Bangor, rated in the king's books at £ 8. 12. 1., and in the patronage of the Bishop of Bangor. The church, dedicated to St. Madryn, is an ancient structure, in the early style of English architecture. There are places of worship for Independents and Calvinistic and Wesleyan Methodists, with Sunday schools attached to each. David Lloyd, in 1686, bequeathed £20 to the poor; Robert Roberts, in 1756, gave £ 12 to be distributed in bread ; and Mrs. Jones, near Corwen, and her daughter-in-law, bequeathed £ 180, directing that the interest should be appropriated to the annual distribution of £4, in sums of five shillings each, to sixteen poor women, and the remaining £ 4. 10. to the apprenticing of a poor boy once in two years. There are some remains of an ancient fortress called Castell Prysor, the name of which implies its hasty erection : it is of small extent, and occupied a situation in a pass between the hills on the left of the road from Trawsvynydd to Bala. The origin of this fortress, which is built of stone without any cement, is not precisely known; but, from the discovery of several urns and coins near the site, it is supposed to have been either built or occupied by the Romans ; and part of a Roman road, now called " the Sarn Helen," which is still visible at no great distance, in some degree corroborates this opinion. On a farm in this parish, called Llech Idris, is Bedd Porus, or " the grave of Porus," over which is a flat stone with the inscription " Porus hic in tumulo jacit, homo -pianus fuit." The word pianus has been thought to have been originally Christianus ; but although the letter p has by some been considered an r, it does not appear ever to have been read t, and the interval between it and homo is insufficient for the five preceding letters. Near this spot is an upright stone, called Llech Idris, from which the farm takes its name, and concerning which there is a legend stating it to have derived that appellation from a giant named Idris ; but it appears to be simply one of those monumental stones so frequently found in this country. Near the Sarn Helen are several tumuli, in one of which were found five urns, and several fragments of bricks, which had been placed round them to protect them from injury : there is also a tumulus on a farm called Gwynionydd. Humphrey Lloyd, Bishop of Bangor, was born at Bodyvudda, in this parish, about the year 1600; and Sion and Rhys Cain, both eminent bards, were also natives of this parish. The average annual expenditure for the support of the poor amounts to £552. ( A Topographical Dictionary of Wales by Samuel Lewis, 1833)
