LOUGHOR (LLYCHWYR), a hamlet, in the parish of LLANEDY, hundred of CARNAWLLON, county of CARMARTHEN, SOUTH WALES, 13 miles (N. N. W. ) from Swansea: the population is returned with the parish. The road from Pont-ar-Ddulas to Llandebie passes through the hamlet, and is, for the greater part, carried along the ridge of a hill, which overlooks a valley on each side, the declivities of which are ornamented with thick plantations and enclosures. The Loughor river bounds it on the east, and separates the parish from Glamorganshire. Anthracite coal of the best quality is found here, and an extensive colliery has recently been opened, called the " Pontyfynnon," within a quarter of a mile of the Llanelly railway, on which are two locomotive engines of considerable power, plying daily between Llanelly and Cwmamman, and which is joined by a branch from this hamlet across the river Loughor.
