LLECHVAEN (LLECH-VAN), a hamlet, forming the upper division of the parish of LLANHAMLLECH in the hundred of PENCELLY, union of BRECKNOCK and county of BRECKNOCK, SOUTH WALES, 2 miles (E. by S.) from Brecknock; containing 113 inhabitants. The present name of this place has a tautological meaning, being literally the "stony stone," corrupted from the ancient etymology, signifying the " upright or lofty stone." It is situated on the southern declivity of the Allt Ronwy mountain, and near the left bank of the Blnych brook, which falls into the Usk about a mile lower down. A bridge here crosses the Usk, and another the Brecknock canal, which passes nearly contiguous, and just below is conveyed to the right bank of the river by an aqueduct of four arches. The Hay railway, from Brecknock to King-ton and Eardisley in Herefordshire, has been carried through this hamlet, a little to the south of the village of Ll&hvaen. Here was formerly a chapel of ease to the mother church of Llanhamilech, which fell down about a century ago, and has not since been rebuilt, owing to the latter being sufficiently capacious, and centrally situated, so as to accommodate the inhabitants of all parts of the parish. The Roman Pia Julia Montana anciently traversed the hamlet, in its approach to the Gaer near Brecknock, from the station in the parish of LlanvihangelCwmdfi.
