DYFRYN-ELLAN (DYFRYN-ELAIN), a township, in the parish of CWM-TOYDDWR, hundred of RHAIADR, county of RADNOR, SOUTH WALES, 4 miles (S. w.) from Rhaiadr, containing 360 inhabitants. This township takes its name from the river Elain, the vale of which abounds with romantic scenery, composed of lofty mountains and rugged and precipitous rocks, which are finely contrasted with the verdant meadows and cultivated enclosures on the banks of the river. Cwm Ellan, a neat modern structure, situated on a bend of the river, became the residence of Thomas Grove, Esq., on his purchasing about ten thousand acres of land in this vicinity, with the lordship of the Grange, which by judicious improvement has, from a barren waste, been converted into a fertile and flourishing tract, thus softening the wildness of the mountain scenery which characterizes this secluded spot: this beautiful and romantic seat is now the property of Robert Peel, Esq. At Nant Wyllt, four miles from the mother church, on the left bank of the river Clarwen, is a chapel of ease, a small neat edifice, built in 1772, and in the gift of the vicar; and at Coed y Mynach, or " the Monk's Wood," on the banks of the Elain, about halfway to the mother church, are the remains of an ancient chapel, called Capel Madoc, which is supposed to have been attached to the abbey of Strata Florida, in Cardiganshire, as the vestiges of an ancient road, which connected the two places, are still visible on the lofty hills in this district. There are lead mines in this township, but they are not worked at present.
