The England–Wales border is the official border and mark of entry between Wales and England, two of the four countries of the United Kingdom.〔(【引用サイトリンク】title=The Countries of the UK )〕 It runs for 257 km (160 miles) from the Dee estuary, in the north, to the Severn estuary in the south. It has followed very broadly the same line since the 8th century, and in part generally follows the line of Offa's Dyke, a linear earthwork. However, the modern boundary was essentially fixed in 1535/36, when the former marcher lordships which occupied the border area were abolished and new county boundaries were created. The administrative boundary of Wales was confirmed in the Local Government Act 1972, which was implemented in 1974. Whether Monmouthshire, created in 1535/36, was part of Wales, or an English county treated for most purposes as though it were Welsh, was also settled by the 1972 Act, which included it within Wales. == Geography == The modern boundary between Wales and England runs from the salt marshes of the Dee estuary adjoining the Wirral Peninsula, across reclaimed land to the River Dee at Saltney just west of Chester. It then loops south to include within England an area south-west of Chester, before rejoining the Dee, and then loops east of the river to include within Wales a large area known as Maelor, formerly an exclave of Flintshire, between Bangor-on-Dee (in Wales) and Whitchurch (in England). Returning to the River Dee as far as Chirk, the boundary then loops to the west, following Offa's Dyke itself for about 2 miles, and including within England the town of Oswestry, before reaching the River Vyrnwy at Llanymynech. It follows the Vyrnwy to its confluence with the River Severn, and then continues southwards, rising over Long Mountain east of Welshpool. East of Montgomery, the boundary again follows the line of Offa's Dyke for about 2 miles, before looping eastwards to include within Wales a large area near Churchstoke. It then runs westwards to the River Teme, and follows the river south-eastwards through Knighton before turning south towards the River Lugg at Presteigne, which is within Wales. The boundary continues southwards across hills to the River Wye, and follows the river upstream for a short distance to Hay-on-Wye, on the Welsh side of the border. It continues southwards and rises through and across the Black Mountains, following the Hatterall Ridge past Llanthony on the Welsh side and Longtown on the English side, to reach the River Monnow near Pandy. It then generally follows the river, past Pontrilas (in England) and Skenfrith (in Wales), towards Monmouth, looping eastwards to include the town itself and a surrounding area within Wales. At Redbrook, the boundary again reaches the Wye, and follows the river southwards, past Tintern and Chepstow on the Welsh side, to its confluence with the Severn at the Severn Bridge. The boundary then continues down the Severn estuary towards the Bristol Channel, with the small island of Flat Holm being administered within Wales and the neighbouring island of Steep Holm within England. === Administrative boundary === The boundary passes between the current local authority principal areas of Flintshire, Wrexham, Powys and Monmouthshire, in Wales; and Cheshire West and Chester, Shropshire, Herefordshire and Forest of Dean district of Gloucestershire, in England. In relation to the historic counties, it passes between the historic counties of Flintshire, Denbighshire, Montgomeryshire, Radnorshire, Brecknockshire and Monmouthshire on the Welsh side; and Cheshire, Shropshire, Herefordshire and Gloucestershire on the English side. There are several places where the border runs along the centre of a lane or street, resulting in properties on one side of the street being in Wales and those on the other side being in England. Notable examples include Boundary Lane in Saltney and the main street of Llanymynech. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「England–Wales border」の詳細全文を読む スポンサード リンク
