Caeron, on Mynydd y Rhiw mountain; Castell Odo, on Mynydd Ystum; and two on Mynydd Cilan, in the parish of Llan Engan. Several eminences bear the name of Pen yr Orsedd, i.e. the Throne, or Seat of Judicature, two of these are not far distant from Nevin; and near Cefnamwlch is a Cromlech, called Coetan Arthur. The following wells may also be mentioned as remarkable, on account of their bearing the names of British Saints; viz. Ffynnon Saint, Ffynnon Ddurdan, Ffynnon Cefn Llaethfaen, Ffynnon Eliw, in the Parish of Rhiw; Ffynnon Garmon, in Aberdaron, and Ffynnon Lleuddad, in Bryncroes. Aberdaron is a small fishing Village, situated on a sandy Bay, at the extremity of the Promontory of Lleyn (_Langanum Promontorium_); the mouth of the Bay is protected by two little Islands, called _Ynys Gwylan_; it takes its name from the rivulet _Daron_, which here empties itself into the sea; the inhabitants are mostly fishermen. The Church, which consists of two aisles, supported by four handsome pillars, is dedicated to St. Hoywyn; it was a sanctuary, and much frequented by pilgrims; Leland says it was called Llan Engan Frenin, (_Fanum Niniani Reguli_), but it is very probable, that the transcribers of his work must have made a mistake, as _Llan Engan_ is seven or eight miles distant, on the road to Pwllhely, and where there is a very curious inscription on the Steeple, copied and explained by Mr. Rowlands. The Rectorial Tithes belong to St. John’s College, Cambridge; the Vicarage is in the patronage of the Bishop. This and Porth Meudwy, (a small Creek near it) were the places where Devotees, in former times, usually embarked for Bardsey (Enlli), and the curious stranger, who may wish to visit that Island, can easily procure a boat here, but before he sets sail he should examine the ruins of St. Mary’s Chapel (Capel Fair), and also our Lady’s Cave and Well, (Ogof Mair a Ffynnon Fair,) the former is situated in a small plain, between two hills, Uwch Mynydd a Mynydd y Gwyddel, and the latter not far distant, nearly at the foot of a dreadful precipice called Maen Melyn, and from which, no doubt, this Commot (Cwmmwd-maen) takes its name. There is a most hazardous and circuitous path, down to the Cave and Well, along which Devotees frequently descended in former days, and even at the present time many are induced to visit the spot from curiosity. Maen Melyn is a yellow rock, streaked with white veins, in the middle of a black precipice, and at a distance has much the appearance of a large dog or leopard. In the dark ages of Popish Superstition it was supposed that if a person could descend by this path, and bring up a mouthful of water from the well, his wish would be certainly fulfilled; the Cape, at the end of the Promontory is called _Penyccil_, and the ridge of hills Braich y pwll. This Chapel was placed here, in all probability, to give the seamen an opportunity of invoking the tutelar Saint for protection through this dangerous Sound.
