In 1870-72, John Marius Wilson's Imperial Gazetteer of England and Wales described Trecastle like this:
TRECASTLE, a village in Llywell parish, Breconshire; on the Brecon and Llandovery railway, under T.-Beacon mountain, 11 miles W of Brecon. It has a post-office under Brecon, an inn, and seven annual fairs. A castle was founded adjacent to it by Bernard Newmarch; and is now represented by a mound and extensive earthworks. T.-B. mountain is 2,594 feet high.
