. "Buellt or Builth was a cantref in medieval Wales, located west of the River Wye. Unlike most cantrefs, it was not part of any of the major Welsh kingdoms for most of its history, but was instead ruled by an autonomous local dynasty. During the Norman era it was associated with Rhwng Gwy a Hafren, a region independent of the Welsh monarchies and controlled by Norman Marcher Lords. In the 16th century, it was reorganized as a hundred and joined with the former kingdom of Brycheiniog to form the county of Brecknockshire. In the 16th century, as part of Henry VIII's Laws in Wales Acts, Buellt became a hundred and merged with Brycheiniog into the new county of Brecknockshire. In 1996 the area became part of the modern county of Powys. The cantref's name survives in the modern town of Builth Wells and the site of nearby Builth Castle."@en . . "Builth Wells"@en . .
