GWASTEDYN (GWASTADEDD-VAWR), a township, in the parish of NANTMEL, hundred of Rhaiadr, county of RADNOR, SOUTH WALES, 2
miles (E. by S.) from Rhaiadr, containing 423 inhabitants. It is situated at the western extremity of the parish, and a
great part of it is occupied by a very lofty hill, on which one of the largest, if not the most perfect, carneddau in the
county is found. It consists of a large pile of stones, supposed to contain between thirty and forty cart-loads, thrown
into nearly a square form, with a hollow in the centre; but this ancient sepulchral monument has sustained so much injury
from the destructive effect of ages, that few traces of order are now observable in its construction. Dyfryn wood
terminates the declivity of this hill on the west; and the valley on the east is populous and well cultivated. The road
from Builth to Rhaiadr passes along the left bank of the river Elain, which bounds the township, parish, and county on the
southwest.
