Severn Estuary in the context of "Gloucester"

The Romano-British culture arose in Britain under the Roman Empire following the Roman conquest in AD 43 and the creation of the province of Britannia. It arose as a fusion of the imported Roman culture with that of the indigenous Britons, a people of Celtic language and custom.

Scholars such as Christopher Snyder believe that during the 5th and 6th centuries – approximately from 410 when the Roman legions withdrew, to 597 when St Augustine of Canterbury arrived – southern Britain preserved an active sub-Roman culture that survived the attacks from the Anglo-Saxons and even used a vernacular Latin when writing.

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 Wye Valley (Welsh: Dyffryn Gwy) is a valley in Wales and England. The River Wye (Welsh: Afon Gwy) is the fourth-longest river in the United Kingdom.

The upper part of the valley is in the Cambrian Mountains and is enclosed by hills as it descends through Rhayader, Builth Wells and Hay-on-Wye before reaching the England-Wales border and becoming a broader vale through Hereford. The lower part of the valley meanders past Ross-on-Wye and Monmouth, where it becomes the England-Wales border, before reaching the Severn Estuary at Chepstow. Much of this section features limestone gorge scenery and dense native woodlands, which made the Wye Valley historically important as one of the birthplaces of the modern tourism industry.

The River Avon (/ˈeɪvən/ AY-vən) is a river in the southwest of England. To distinguish it from a number of other rivers of the same name, it is often called the Bristol Avon. The name 'Avon' is loaned from an ancestor of the Welsh word afon, meaning 'river'.

The Avon rises just north of the village of Acton Turville in South Gloucestershire, before flowing through Wiltshire into Somerset. In its lower reaches from Bath (where it meets the Kennet and Avon Canal) to the Severn Estuary at Avonmouth near Bristol, the river is navigable and is known as the Avon Navigation.

Penarth (/pɛnˈɑːrθ/ pen-ARTH, Welsh: [pɛnˈarθ]) is a town and community in the Vale of Glamorgan, Wales, approximately 3 miles (4.8 km) south of Cardiff city centre on the west shore of the Severn Estuary at the southern end of Cardiff Bay.

Penarth is a seaside resort in the Cardiff Urban Area, and the second largest town in the Vale of Glamorgan, next only to the administrative centre of Barry.

Monmouthshire (/ˈmɒnməθʃər, ˈmʌn-, -ʃɪər/ MON-məth-shər, MUN-, -⁠sheer; Welsh: Sir Fynwy) is a county in the south east of Wales. It borders Powys to the north; the English counties of Herefordshire and Gloucestershire to the north and east; the Severn Estuary to the south, and Torfaen, Newport and Blaenau Gwent to the west. The largest town is Abergavenny, and the administrative centre is Usk.

The county is rural, although adjacent to the city of Newport and the urbanised South Wales Valleys. It has an area of 330 square miles (850 km) and a population of 94,930. Abergavenny is located in the north-east, and Usk in near the centre; other settlements include Monmouth in the east, Chepstow in the south-east, Caldicot in the south. Monmouthshire County Council is the local authority. Monmouthshire was established in 1996 and is named after the historic county of the same name, of which it covers approximately the eastern three-fifths. The county has one of the lowest percentages of Welsh speakers in Wales, at 8.2% of the population in 2021.

The North Somerset Levels is a coastal plain, an expanse of low-lying flat ground, which occupies an area between Weston-super-Mare and Bristol in North Somerset, England. The River Banwell, River Kenn, River Yeo and Land Yeo are the three principal rivers draining the area.

To the south the levels are bounded by the Mendip Hills, to the east by the Yeo Valley and the Lulsgate Plateau, and to the north by the Tickenham Ridge. To the west lies the Severn Estuary.
