Brecon Castle (Welsh: Castell Aberhonddu) is a castle in the town of Brecon, Wales. It was built by the Norman Lord Bernard de Neufmarché in 1093, and was frequently assaulted by the Welsh in 13th and 15th centuries. The castle's ownership changed numerous times. It began falling into ruin when Henry VIII executed the last dukes of Buckingham, who at the time controlled the castle. It was renovated and made into a hotel in the early 19th century.
