ABERBAIDON (ABER-BAIDEN), a hamlet, in the parish of LLANELLY, hundred of CRICKHOWEL, county of BRECKNOCK, SOUTH WALES,
5 miles (w. by N.) from Abergavenny. The population is returned with the parish. This place derives its name from being
situated at the junction of a small river, called the Baideu, with the Usk. It is intersected by the river Clydach, which
passes through a deep valley to its confluence with the Usk, and in its course forms several cascades, the most remarkable
of which was called Pwll y Cwn, or " The Dog's Pool," now converted to manufacturing purposes. The Brecknock canal is
carried over this river by means of an embanked aqueduct, eighty-four feet above the bed of the river, and communicates
with different rail-roads, formed in connexion with some lime and coal works situated within the limits of the hamlet,
which, together with the Clydach iron-works, afford employment to a large proportion of the inhabitants, and the produce
of which is distributed, by means of the canal, throughout the adjacent district. On the south side of a hill, at the base
of which flows the Clydach, there are the remains of an ancient British fortress, called the Gaer. This hamlet supports
its own poor: the average annual expenditure is £199. 17.
