LLANSADWRN (LLAN-SADWRN), a parish in the hundred of TYNDAETHWY, county of ANGLESEY, NORTH WALES, 3 1/2 miles (W.) from Beaumaris, containing 371 inhabitants. This parish, which is situated in the eastern part of the county, and within four miles of the Menai bridge, comprises a moderate portion of land, of which the whole is enclosed, and the greater part in a state of good cultivation. The houses of the inhabitants are scattered over the parish in detached situations, not forming any village ; and the surrounding scenery, though not characterized by any peculiarity of feature, is pleasingly rural. The living is a discharged rectory, in the archdeaconry of Anglesey, and diocese of Bangor, rated in the king's books at £ 7. 6. 0 1/2., and in the patronage of the Bishop of Bangor. The church, dedicated to St. Sadwrn, from which circumstance the parish derives its name, is a small but neat edifice, consisting of a nave, chancel, and north transept, and was thoroughly repaired at a considerable expense in 1829. In the transept, projecting from one of the walls, is the head of an ecclesiastic, well executed in stone; and outside the same part of the edifice is the head of a bear, with a muzzle and chain, also curiously carved in stone. A fragment of stone has been found, which is now placed within the transept under the head above mentioned, bearing part of. a mutilated inscription in Roman characters, in which the word " Saturninus," still legible, seems to shew that it was part of the monument of that saint, by whom the church is supposed to have been founded about the year 603. The farms of Bryn Eryr and Rhos Owen, left by Dr. Rowlands for the support of his almshouses at Bangor, are in this parish. Rowland Jones, in 1715, left a tenement called Gorslas, the rent of which he appropriated in equal shares to the poor of this parish and that of Pentraeth ; and Mrs. Roberts, in 1756, bequeathed £ 150, the interest of which sum she directed to be given in equal shares to three of the poorest and most deserving housekeepers of Llansadwrn. In a field adjoining Trevor, in this parish, are the remains of two ancient cromlechs ; the larger, which was supported on two upright stones more than ten feet high, fell down in 1825. There are some remains of an ancient fortress, near an old, family mansion called " Castellior," which, from several relics of antiquity discovered in the immediate vicinity, is supposed to be of Roman origin. In the marsh near the base of Llwydiart mountain, fossil oak trees, acorns, and nuts are found, several feet below the surface, retaining all their original freshness. The poor are maintained by an average annual expenditure amounting to £137. 10. ( A Topographical Dictionary of Wales by Samuel Lewis, 1833)
