KILLEY (CIL-LE), a parcel, joint with Prysg, in the parish of LLANGATTOCK, hundred of CRICKHOWEL, county of BRECKNOCK,
SOUTH WALES, 1 mile (w.) from Crickhowel. The population is included in the return for the parish. It is situated in a
pleasing vale, through which k stream flows into the river Usk, and abounds with limestone, the quarrying and burning of
which give employment to a great portion of the inhabitants: a railway proceeds from the quarries to the Brecknock canal,
which crosses the hamlet. The ancient and extensive park of C11-le Lan was formerly an appendage of the castle of
Crickhowel, at the other side of the river Usk, with which there was a connexion by a private bridge, which has long since
been demolished, but its abutments were discovered about fifty years ago, when a high flood carried away a part of the
soil of the river. Within the limestone rock, in a recess of the mountain, termed Darren y is a cave of considerable
dimensions, called Eglwys Vaen, or "the Stone Church." There are two large carneddau on the Carno mountain, where a
sanguinary battle was fought between Ethelbald King of Mercia and Roderic Molwynog, a prince of North Wales, in which the
latter is said to have been victorious.
