CAPEL-CALLWEN, or BLAEN-GLYNTAWE, a chapelry, attached to the parish of DEVYNOCK, in the hundred of DEVYNOCK, county of BRECKNOCK, SOUTH WALES, 15 miles (W. S. W.) from Brecknock, containing 89 inhabitants. It is situated at the south-western extremity of the extensive parish of Devynock, in a vale between elevated and dreary mountains, not far from the source of the river Tawe. The country about the head of this vale is strikingly romantic. Limestone rocks rise to a great height, and, being in some places totally destitute of vegetation, present the appearance of ruined castles and other picturesque combinations; but the most remarkable is an extensive, irregular, and isolated one, in horizontal strata, called the Cribarth lime-rock, which rises out of the valley to an extraordinary height. Descending from the Great Forest of. Devynock into the vale, a patch of thriving firs near the foot of a bold eminence, and the scattered cottages, all white- washed, have a most pleasing and lively effect in the midst of a scene remarkable for its wild and barren aspect. In the chapelry arc found some calm and iron-stone, with abundance of limestone; and Chrisde's railway, constructed for the purpose of conveying this produce to other parts of the county, passes along the sides of the mountains, and through the glens which intersect them near Devynock, to the river Usk. The living is a perpetual curacy, in the archdeaconry of Brecknock, and diocese of St. David's, endowed with £800 royal bounty, and £200 parliamentary grant, and in the patronage of the Vicar of Devynock. At this place is one of " the Lord's Mills," to which the inhabitants are obliged to send their corn to be ground, a relic of the ancient feudal tenure; but the right is not now rigidly enforced. This chapelry separately supports its own poor: the average annual expenditure down to 1826 was 414, but since that period there have been no poor receiving relief.
