LLANSADWRN (LLAN-SADWRN), a parish, in the union of BANGOR-AND-BEAUMARIS, hundred of TYNDAETHWY, county of ANGLESEY, NORTH
WALES, 3 miles (W.) from Beaumaris; containing 455 inhabitants. This parish, which is situated in the eastern part of the
county, within four miles of the Menai bridge, and on the road from Llangevni to Beaumaris, is bounded on the north by the
parishes of Pentraeth and Llanddona, on the south by that of Llandegvan, on the east by Beaumaris, and on the west by
Penmynnedd; and comprises by computation 2891 acres, of which 1700 are arable, 1103 pasture, and the remainder woodland
and waste. The lands are in general inclosed and well cultivated; the soil is fertile, and the chief produce corn, cattle,
and a few sheep. The houses of the inhabitants are scattered over the parish in detached situations, not forming any
village; and the surrounding scenery, though not characterised by any peculiarity of feature, is pleasingly rural. The
living is a discharged rectory, rated in the king's books at £7. 6. Of.; patron, Bishop of Bangor: the tithes have been
commuted for a rent-charge of £400. 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; it contains 140 sittings, of which 50 are free. 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 chew that it was part of the monument of that saint, by whom the church is
supposed to have been founded about the year 603. There are two Sunday schools, in which about 50 males and females are
gratuitously instructed by some of the parishioners. 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, be3ueathed a tenement called Gorslis, the
rent of which he appropriated in equal shares, amounting to a. 5. for each, to the poor of this parish and that of
Pentraeth; and Mrs. Roberts, in 1756, left £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: this last sum was invested in a mortgage on the tolls
of the Holyhead road, and now produces an income of £7. 10. annually; and the amount of both charities is distributed at
Easter and Christmas among the most necessitous poor. With numerous other benefactions, amounting in the whole to £41, the
principal contributors to which were Humphrey Williams, in 1741, and Griffith Rowland, in 1765, of sums of £10 each, ten
small cottages were erected on ground granted by the late Lord Bulkeley at £1. 1. per annum; they are now occupied rent
free by ten families put in by the vestry. In a field adjoining Trevor, in the parish, are the remains of two cromlechs;
the larger, which was supported on two upright stones more than ten feet high, fell down in 1825. There are also some
vestiges 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.
