Blaenllynfi Castle

Blaenllyfni 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.
