Through Archaeology, Paleolithic and Iron Age

The city is the twenty-eighth largest in the United Kingdom. Located along Swansea Bay in south-west Wales, with the principal area covering the Gower Peninsula, it is part of the Swansea Bay region and part of the historic county of Glamorgan and the ancient Welsh commote of Gŵyr.

The principal area is the second most populous local authority area in Wales, with an estimated population of 249,429 in 2025. At the 2021 census the population was 238,500, this was 0.2% lower than the population at the time of the 2011 census when it was 239,023. Swansea, along with Neath and Port Talbot, forms the Swansea urban area, with a population of 300,352 in 2011. It is also part of the Swansea Bay City Region.

During the 19th-century industrial heyday, Swansea was the key centre of the copper-smelting industry, earning the nickname Copperopolis.

Toponymy

Welsh names

The Welsh name, Abertawe, translates as "mouth or estuary of the Tawe" and was likely used as a name for the area before a settlement was established. The Welsh name Abertawe was first recorded with written records dating from 1150, under the spelling Aper Tyui.

Thomas Morgan notes that the original name of the town was Caer Wyr, meaning the "Caer" of Gower. and was the name used by the fifteenth century bard Lewis Glyn Cothi in reference to a great fortress that stood in the Swansea area, but was in ruins by his time.

English name

The name Swansea first appears as Sweynesse in the town's first Royal charter (1158–1184), with alternative versions of this name found on coins minted around 1140. First appearing as "Sweynsei" in 1188 and "Sweineshie" in 1234, with different derivations gaining favour over the centuries. In 1722, the antiquarian Thomas Hearne stated that a "King Swanus" and his entire fleet were drowned at "Swenawick, alias Swanesey" a name he derived as "the sea of Swanus". The most prevalent theory was that the name derived from "swine sea", due to the large number of porpoises in Swansea Bay.

Today the English name is believed to be Old Norse in origin, with a popular etymology stating that it derives from a Viking personal name 'Svein' or 'Sweyn', with the suffix of '-ey' ("island"), referring either to a bank of the river at its mouth or to an area of raised ground in marshland. However, the Norse termination -ey can mean "inlet", and the name may simply refer to the mouth of the river. It is also commonly stated that the eponym of the city is in fact Sweyn Forkbeard (c. 960–1014).
