Brecon (Welsh: Aberhonddu), archaically known as Brecknock, is a market town and community in Powys, Mid Wales, with a population of 7,901. Historically it was the county town of Brecknockshire; although its role as such was eclipsed with the formation of the County of Powys, it remains an important local centre. Brecon is the third largest town in Powys, after Newtown and Ystradgynlais. It lies north of the Brecon Beacons mountain range, but is just within the Brecon Beacons National Park.
