LLANSADWRNEN (LLAN-SADYRNIN), a parish, in the higher division of the hundred of DERLLYS, union of CARMARTHEN and county of CARMARTHEN, SOUTH WALES, 2 miles (S. W.) from Laughame; containing 237 inhabitants. This parish, which derives its name from the dedication of its church, is pleasantly situated on the bay of Carmarthen, and is but if small extent; the land is inclosed and in a tolerable state of cultivation. Limestone is found in the rocks near the coast, but the inhabitants are principally employed in agriculture. The surrounding scenery is pleasingly varied; and the views, extending over the bay and the adjacent country, are interesting, and combine some features of picturesque character. The living is a rectory, annexed to the vicarage of Laugharne, and rated in the king's books at £6. In the parish are the remains of Broadway House, an ancient mansion, formerly the residence of John Powel, Esq., Chief Justice of the Common Pleas, and Keeper of the Great Seal in the reign of James II.; he was one of the judges who sat on the trial of the seven bishops that were committed to the Tower by order of that monarch, in 1688, and by his inflexible integrity they were absolved of the charge laid against them: he died in 1696, aged sixty-three, and was buried in the chancel of the church of Laugharne, where a monument was erected to his memory, bearing an inscription eulogizing his conduct on that memorable trial. In the limestone rock near the coast is a curious and beautiful cavern of large dimensions, which was formerly a retreat for smugglers.
