Radnorshire (Sir Faesyfed) is almost entirely within the mountains. It has no large towns. Its hills are uncultivatable but rich in sheep grazing, and a delight for wild-country enthusiasts. The southern part of the county is taken up by the Radnor Forest, a place of moors, woods and rivers. There are rich valleys where rivers run down through the hills. The River Wye rises above Rhayader, and these upper stretches are very picturesque. Hereabouts too are the Elan Valley Lakes. The Wye marks Radnorshire’s southern border with Brecknockshire. Its northern borders are with Shropshire on the River Teme and with Montgomeryshire. New Radnor, the county town, was founded and named by Earl Harold Godwinsson (later King Harold II) at the conclusion of his campaign in Wales. It is a small market town with impressive earthworks and a fallen castle. Nearby is the Water-Break-its-Neck waterfall. The picturesque rolling countryside of the Teme Valley around Knighton has been noted. Knighton itself sits astride the border of Radnorshire and Shropshire.
