LLANMADOCK, a parish, in the union and hundred of SWANSEA, county of GLAMORGAN, SOUTH WALES, 15 miles (W.) from Swansea; containing 269 inhabitants. This parish is situated on Whitford-harbour, at the mouth of the Burry river; and is bounded on the east by the parish of Cheriton, and on the south by that of Llangennith; it comprises 450 acres, of which the arable and pasture lands are in nearly equal portions. The most striking feature on its surface is Llanmadock hill, which is generally considered as the highest point in the peninsula of Gower, and is a well-known landmark to mariners off this part of the coast, and the view from which is extensive and magnificently grand, comprising the whole of the peninsula of Gower, the entire course of the Loughor or Burry river from Pont-ar-Ddulas to its mouth, the luxuriant woods of Penrice Castle, the lofty and precipitous cliffs that form the eastern side of Oxwich bay, with the vast expanse of sea beyond, the Devon and Cornish hills in the distance, and the coasts of Pembrokeshire and Carmarthenshire. The soil consists of a reddish-brown earth, resting upon gravel, with a substratum of limestone; and the chief produce is barley and wheat. The village, called Troglane, extends about half a mile along the base of the hill: the land in the parish is chiefly inclosed and in a good state of cultivation. The place carries on a considerable trade in coal and limestone, irk which about thirty vessels, varying in burthen from twelve to twenty tons, are employed: in these vessels the coal is brought from Loughor and Llanelly, and the limestone conveyed to the counties of Devon and Cornwall. The living is a rectory, rated in the king's books at £9, and in the patronage of the. Crown; present net income, £112. The church, dedicated to St. Madoc, the son of Gildas, a saint in Gower, was rebuilt in 1748, and is 50 feet long and 18 broad. There is a place of worship for Welsh Calvinistic Methodists. On Llanmadock hill are traces of an ancient encampment, comprising a nearly circular area of about four acres, defended by triple ramparts, and commanding the entrance of the Burry river.
