South Wales is in the United Kingdom. These are historic counties used for geographic purposes. Due to the large populations of Glamorgan and Monmouthshire they are divided into twelve local authorities called "council areas", namely Swansea, Neath Port Talbot, Rhondda Cynon Taf, Bridgend, Vale of Glamorgan, Cardiff, Newport, Monmouthshire, Torfaen, Blaenau Gwent, Caerphilly and Merthyr Tydfil.
Swansea is a city on the South Wales coast. With a population approaching 250,000, it is the second largest city in Wales, and located on the beautiful Gower Peninsula - the United Kingdom's first designated "Area of Outstanding Natural Beauty".
