Wales-England border in the context of "Coastline of Wales"

Chirk (Welsh: Y Waun) is a town and community in Wrexham County Borough, Wales, 10 miles (16 kilometres) south of Wrexham, between it and Oswestry. At the 2011 census, it had a population of 4,468. Historically in the traditional county of Denbighshire, and later Clwyd, it has been part of Wrexham County Borough since a local government reorganisation in 1996. The border with the English county of Shropshire is immediately south of the town, on the other side of the River Ceiriog.

The town is served by Chirk railway station and the A5/A483 roads.

The Welsh Marches (Welsh: Y Mers) is an imprecisely defined area along the border between England and Wales in the United Kingdom. The precise meaning of the term has varied at different periods.

The English term Welsh March (in Medieval Latin Marchia Walliae) was originally used in the Middle Ages to denote the marches between England and the Principality of Wales, in which Marcher lords had specific rights, exercised to some extent independently of the king of England. In modern usage, "the Marches" is often used to describe those English counties which lie along the border with Wales, particularly Shropshire and Herefordshire, and sometimes adjoining areas of Wales. However, at one time the Marches included all of the historic counties of Cheshire, Shropshire, Herefordshire, Worcestershire and Gloucestershire.

Chepstow (Welsh: Cas-gwent) is a town and community in Monmouthshire, Wales, adjoining the border with Gloucestershire, England. It is located on the tidal River Wye, about 2 miles (3 km) above its confluence with the River Severn, and adjoining the western end of the Severn Bridge. It is the easternmost settlement in Wales, situated 16 miles (26 km) east of Newport, 28 miles (45 km) east-northeast of Cardiff, 18 miles (29 km) northwest of Bristol and 110 miles (180 km) west of London.

Chepstow Castle, situated on a clifftop above the Wye and the old bridge, is often cited as the oldest surviving stone castle in Britain. The castle was established by William FitzOsbern immediately after the Norman Conquest, and was extended in later centuries before becoming ruined after the Civil War. A Benedictine priory was also established within the walled town, which was the centre of the Marcher lordship of Striguil. The port of Chepstow became noted in the Middle Ages for its imports of wine, and also became a major centre for the export of timber and bark, from nearby woodland in the Wye Valley and Forest of Dean. In the late eighteenth century the town was a focus of early tourism as part of the "Wye Tour", and the tourist industry remains important. Other important industries included shipbuilding – one of the First World War National Shipyards was established in the town – and heavy engineering, including the prefabrication of bridges and wind turbine towers. Chepstow is also well known for its racecourse, which has hosted the Welsh National each year since 1949.

The River Wye (/waɪ/; Welsh: Afon Gwy [ɡʊɨ̯]) is the fourth-longest river in the UK, stretching some 250 kilometres (155 miles) from its source on Plynlimon in Mid Wales to the Severn Estuary. The lower reaches of the river form part of the border between England and Wales. The Wye Valley (lower part) is designated a National Landscape (formerly an Area of Outstanding Natural Beauty). The Wye is important for nature conservation and recreation, but is affected by pollution.
