Wales is bounded by the Irish Sea (N), by the Bristol Channel (S), by the English counties of Cheshire, Shropshire, Herefordshire, and Gloucestershire (E), and by Cardigan Bay and St. George's Channel (W).
Wales comprises 22 administrative divisions (unitary authorities): Flintshire, Wrexham, Denbighshire, Conwy, the Isle of Anglesey, Gwynedd, Powys, Ceredigion, Pembrokeshire, Carmarthenshire, Swansea, Neath Port Talbot, Bridgend, the Vale of Glamorgan, Rhondda Cynon Taf, Merthyr Tydfil, Cardiff, Caerphilly, Blaenau Gwent, Torfaen, Newport, and Monmouthshire.
Wales was legally annexed by the Laws in Wales Act 1535, in the reign of Henry VIII of England, who was himself partly of Welsh ancestry.
