From the Wikipedia article
Blaenllynfi Castle (Welsh: Castell Blaenllynfi) is a privately owned ruinous stone castle near the village of Bwlch in southern Powys, Wales. It was probably built in the early thirteenth century. It was captured several times during the rest of the century and apparently was never fully repaired afterwards and fell into ruins. It is a Scheduled Ancient Monument.

Background
History
It was the (head) of the Marcher Lordship of Blaenllynfi (the lands of which later became the barony of Talgarth). The Lordship was created in 1208, from part of the Lordship of Brecknock, when the Lord of Brecknock (William de Braose) fell out with King John in a spectacularly bad manner. The first Marcher Lord of Blaenllynfi was Peter FitzHerbert, William's cousin; their mothers were co-heirs of William de Hereford, former Lord of Brecknock. The castle was therefore most likely constructed in 1208–15; after that period the Braose family briefly managed to re-assert control over Blaenllynfi, as part of the general insurrection against King John, before the Lordship of Blaenllynfi was…
Description
The castle covered an area of approximately 78 by within a moat with dimensions of 120 by. The remains of walls, buttresses and towers can be found inside and they have been partially excavated by the owner. The site is an Ancient Scheduled Monument.
