Powys

Powys (/ˈpoʊɪs, ˈpaʊɪs/ POH-iss, POW-iss, Welsh: [ˈpou̯ɪs]) is a county and preserved county in Wales. It borders Gwynedd, Denbighshire, and Wrexham to the north; the English ceremonial counties of Shropshire and Herefordshire to the east; Monmouthshire, Blaenau Gwent, Merthyr Tydfil, Caerphilly, Rhondda Cynon Taf, and Neath Port Talbot to the south; and Carmarthenshire and Ceredigion to the west. The largest settlement is Newtown, and the administrative centre is Llandrindod Wells.

Powys is the largest and most sparsely populated county in Wales, having an area of 2,000 square miles (5,200 km²) and a population of 133,200. After Newtown (11,362), the most populous settlements are Ystradgynlais (8,270), Brecon (8,254), and Llandrindod Wells (5,602). The county is entirely rural, and characterised by multiple market towns and villages. The Welsh language can be spoken by 16.4% of the population.

The county is predominantly hilly and mountainous. To the west lie the Cambrian Mountains, where the River Severn and River Wye both have their source on the Powys side of the Plynlimon massif; together with their tributaries they drain most of the county. The southern quarter of the county is occupied by the Brecon Beacons (Bannau Brycheiniog) national park, and further north are two more upland areas, Mynydd Epynt and Radnor Forest. The only extensive area of flat land in Powys is the region northwest of Welshpool.

The county is named after the Kingdom of Powys, which was a Welsh successor state, petty kingdom and principality that emerged during the Middle Ages following the end of Roman rule in Britain. Powys covers the same area as the historic counties of Montgomeryshire, Radnorshire, and Brecknockshire.
