South Wales in the context of "Cambrian Mountains"

Cambro-Normans (Latin: Cambria; "Wales", Welsh: Normaniaid Cymreig; Norman: Nouormands Galles) were Normans who settled in southern Wales and the Welsh Marches after the Norman invasion of Wales. Cambro-Norman knights were also the leading force in the Cambro-Norman invasion of Ireland, led by Richard de Clare, 2nd Earl of Pembroke in 1170.

The Welsh (Welsh: Cymry) are an ethnic group and nation native to Wales who share a common ancestry, history and culture. Wales is one of the four countries of the United Kingdom. The majority of people living in Wales are British citizens.

In Wales, the Welsh language (Welsh: Cymraeg) is protected by law. Welsh remains the predominant language in many parts of Wales, particularly in North Wales and parts of West Wales, though English is the predominant language in South Wales. The Welsh language is also taught in schools in Wales; and, even in regions of Wales in which Welsh people predominantly speak English on a daily basis, the Welsh language is spoken at home among family or in informal settings, with Welsh speakers often engaging in code-switching and translanguaging. In the English-speaking areas of Wales, many Welsh people are bilingually fluent or semi-fluent in the Welsh language or, to varying degrees, capable of speaking or understanding the language at limited or conversational proficiency levels. The Welsh language is descended from Brythonic, spoken across Britain since before the Roman invasion.

The Roman era in the area of modern Wales began in 48 AD, with a military invasion by the imperial governor of Roman Britain. The conquest was completed by 78 AD, and Roman rule endured until the region was abandoned in 383 AD.

The Roman Empire held a military occupation in most of Wales, except for the southern coastal region of South Wales, east of the Gower Peninsula, where there is a legacy of Romanisation in the region, and some southern sites such as Carmarthen, which was the civitas capital of the Demetae tribe. The only town in Wales founded by the Romans, Caerwent, is in South Wales.

Perry or pear cider is an alcoholic beverage made from fermented pears, traditionally in England (particularly Gloucestershire, Herefordshire, and Worcestershire), parts of South Wales, France (especially Normandy and Anjou), Canada, Australia, and New Zealand. Interest is growing in artisanal perry production in the fruit-growing regions of the northwest United States. Perry typically has an alcohol content ranging from 5 to 8% ABV, but is sometimes distilled into calvados with 40-43% ABV, and blended with further pear juice to produce a fortified drink around 17% ABV.

The Bristol Channel (Welsh: Môr Hafren, lit. 'Severn Sea') is a major inlet in the island of Great Britain, separating South Wales (from Pembrokeshire to the Vale of Glamorgan) and South West England (from Devon to North Somerset). It extends from the smaller Severn Estuary of the River Severn (Welsh: Afon Hafren) to the North Atlantic Ocean. It takes its name from the English city and port of Bristol.

Long stretches of both sides of the coastline are designated as Heritage Coast. These include Exmoor, Bideford Bay, the Hartland Point peninsula, Lundy Island, Glamorgan, Gower Peninsula, Carmarthenshire, South Pembrokeshire and Caldey Island.

The coastline of Wales extends from the English border at Chepstow westwards to Pembrokeshire then north to Anglesey and back eastwards to the English border once again near Flint. Its character is determined by multiple factors, including the local geology and geological processes active during and subsequent to the last ice age, its relative exposure to or shelter from waves, tidal variation and the history of human settlement and development which varies considerably from one place to another. The majority of the coast east of Cardiff in the south, and of Llandudno in the north, is flat whilst that to the west is more typically backed by cliffs. The cliffs are a mix of sandstones, shales and limestones, the erosion of which provides material for beach deposits. Of the twenty-two principal areas which deliver local government in Wales, sixteen have a coastline, though that of Powys consists only of a short section of tidal river some distance from the open sea. Its length (including Anglesey) has been estimated at 1,680 miles (2,700 km).

The South Wales Valleys (Welsh: Cymoedd De Cymru) are a group of industrialised peri-urban valleys in South Wales. Most of the valleys run north–south, roughly parallel to each other. Commonly referred to as "The Valleys" (Welsh: Y Cymoedd), they stretch from Carmarthenshire in the west to Monmouthshire in the east; to the edge of the pastoral country of the Vale of Glamorgan and the coastal plain near the cities of Swansea, Cardiff, and Newport.

Coal mining in the United Kingdom dates back to Roman times and occurred in many different parts of the country. Britain's coalfields are associated with Northumberland and Durham, North and South Wales, Yorkshire, the Scottish Central Belt, Lancashire, Cumbria, the East and West Midlands and Kent. After 1972, coal mining quickly collapsed and had practically disappeared by the 21st century. Production fell from 228 million tonnes in 1957 to just 107 thousand tonnes in 2024, while coal consumption fell from 216 million to 2 million tonnes in the same time period. Employment in coal mines fell from a peak of 1,191,000 in 1920 to 695,000 in 1956, 247,000 in 1976, 44,000 in 1993, 2,000 in 2015, and to 360 in 2022.

Almost all onshore coal resources in the UK occur in rocks of the Carboniferous period, some of which extend under the North Sea. Bituminous coal is present in most of Britain's coalfields and is 86% to 88% carbon. In Northern Ireland, there are extensive deposits of lignite which is less energy-dense based on oxidation (combustion) at ordinary combustion temperatures. In 2015, EURACOAL estimated that the UK has 3.56 billion tonnes of hard coal resources.

Ringforts or ring forts are small circular fortified settlements built during the Bronze Age, Iron Age and early Middle Ages up to about the year 1000 AD. They are found in Northern Europe, especially in Ireland. There are also many in South Wales and in Cornwall, where they are called rounds. Ringforts come in many sizes and may be made of stone or earth. Earthen ringforts would have been marked by a circular rampart (a bank and ditch), often with a stakewall. Both stone and earthen ringforts would generally have had at least one building inside.

Isca, variously specified as Isca Augusta or Isca Silurum, was the site of a Roman legionary fortress and settlement or vicus, the remains of which lie beneath parts of the present-day suburban town of Caerleon in the north of the city of Newport in South Wales. The site includes Caerleon Amphitheatre and is protected by Cadw.

Headquarters of the Legion "II Augusta", which took part in the invasion under Emperor Claudius in 43, Isca is uniquely important for the study of the conquest, pacification and colonisation of Britannia by the Roman army. It was one of only three permanent legionary fortresses in later Roman Britain and, unlike the other sites at Chester and York, its archaeological remains lie relatively undisturbed beneath fields and the town of Caerleon and provide a unique opportunity to study the Roman legions in Britain. Excavations continue to unearth new discoveries; in the late 20th century a complex of very large monumental buildings outside the fortress between the River Usk and the amphitheatre was uncovered. This new area of the canabae was previously unknown.
