The county was formed in 1536 from several Marcher lordships under the Laws in Wales Acts, as part of the formal annexation of Wales into the Kingdom of England by Henry VIII. The county was named after New Radnor, which was the original county town. From 1543 onwards the assizes were held alternately at New Radnor and Presteigne, later settling at Presteigne alone. Presteigne then served as the county's administrative centre until 1889 when Radnorshire County Council was established and chose to base itself in Llandrindod Wells instead.
