MAWGAN-in-Pyder, a parish, in the union of St. Columb Major, E. division of the hundred of Pyder and of the county of Cornwall, 3 miles (N. W. by W.) from St. Columb Major; containing 749 inhabitants. This place is on the shore of the Bristol Channel, by which it is bounded on the west, and contains a small cove called Mawgan Porth; the cliffs are remarkably fine, especially at that part called Bodrathan Steps, where is a firm sandy beach three miles in extent, named Trevarrian. The parish comprises by computation 6078 acres, of which 600 are common or waste. Slate, thought to be equal in quality to that of the Dellabole quarries, is procured in vast quantities from the cliffs, and sent to different parts of the kingdom. The village is beautifully situated in a picturesque valley watered by a considerable stream which, at the distance of two miles, falls into the sea between two immense cliffs. A fair for cattle takes place on Midsummer-day; and a court leet and baron is held annually for the manor of Carnanton. The living is a rectory, valued in the king's books at £26. 13. 4., and in the gift of H. Willyams, Esq.: the tithes have been commuted for £605, and the glebe comprises 64 acres. The church is an ancient structure: in the churchyard is a cross with a niche, in which the Crucifixion is sculptured in high relief, with several figures. There is a place of worship for Wesleyans. Lanherne House, long the residence of the lords Arundel, was fitted up by the eighth lord as an asylum for Carmelite nuns, who emigrated from Antwerp, and by such it is still occupied.
