FOREST, a hamlet, in the parish and hundred of TALGARTH, county of BRECKNOCK, SOUTH WALES, 10 miles (S.) from Hay,
containing 134 inhabitants. This hamlet consists of the southern portion of that elevated range, called the Black
mountains, which separates Brecknockshire from Monmouthshire and a detached district of Herefordshire. Talgarth mountain,
in this hamlet, is two thousand four hundred and forty-five feet above the level of the sea; and upon another elevated
hill near it, termed Gager, or the Chair, are loose stone circles, evidently Druidical, shaped as an irregular triangle,
with a large stone for an apex, the whole about sixty feet in circumference. Other similar constructions are found within
a short distance on the southern declivity of this mountain. The remains of Dinas castle are also situated in this hamlet.
They occupy the summit of a detached and conical hill at the foot of the Black mountains, and consist at present of little
more than the foundations, the castle having been destroyed, as is supposed, by the natives of Sir David Gam's party, in
opposition to those of Owain Glyndwr's. This hamlet is wild and dreary in its aspect, affording, in general, only scanty
herbage to the mountain sheep.
