Port Talbot is a coastal industrial town in south Wales, situated on the east side of Swansea Bay at the mouth of the River Afan. Roughly eight miles from Swansea, it forms part of the county borough of Neath Port Talbot.

Port Talbot is on the coast, where the Afan Valley meets the Bristol Channel. It abuts Margam to the south-east and incorporates or borders several historic communities, including Baglan, Aberafan, Talbach, Cwmafan, and Bryn.

Its location made it a natural outlet for mineral-rich valleys, later enabling the development of docks, railways, and large-scale industry. The M4 motorway now skirts the town, reinforcing its role as a transport and industrial hub.

Human presence in the Port Talbot area stretches back thousands of years. Farming ditches on Mynydd Margam and funerary cairns on Margam Mountain indicated early settlement and agriculture during the Bronze Age. Hillforts once crowned Mynydd Dinas, Mynydd Margam, Mynydd Emroch, and other nearby hills, and the remains of an Iron Age village survived on Mynydd Hawdref. Roman roads and activity are evidenced in the Margam area, while inscribed stones such as the Conbelin Cross and the Cross of Brancuf reflect early Christian worship. These discoveries suggest that the region's coastal areas and valleys have long supported communities, agriculture, and trade.

The medieval settlement of Aberafan formed the nucleus of what would become Port Talbot. It served as the seat of the Lords of Afan, a Welsh princely line. Nearby, Margam Abbey, founded in 1147 by Robert, Earl of Gloucester, became one of Wales' wealthiest Cistercian monasteries. Its monks developed extensive agricultural estates, including sheep farming for wool export, and even mined iron and lead by the mid-13th century. The abbey's dissolution in the 1530s led to the estate passing through the Mansel family and later to the Talbots, who would profoundly shape the town's industrial future.

Port Talbot's transformation into an industrial centre began in the 18th century. The English Copper Company established a works at Talbach in 1770, and tinplate production expanded at Margam in the 1820s. The Talbot family oversaw the construction of new docks in 1837 and welcomed the South Wales Railway in 1850, enabling coal and metal exports from the Afan Valley and beyond. By the late 19th century, iron and steel had overtaken copper, and coal exports surged. The town's industries grew rapidly, bringing workers in from across Wales.

The Port Talbot Steelworks opened in 1906 and expanded significantly after World War II, becoming one of the largest integrated steel plants in Europe. At its peak in 1961, it employed over 18,000 workers, earning the town the nickname "City of Steel."

The steelworks dominated both the economy and skyline, symbolising the town's industrial might. Eventually, however, global competition and structural challenges led to decades of uncertainty and decline. In 2024, Tata Steel shut down the plant's blast furnaces, ending over a century of traditional steelmaking. These industrial sites are now transitioning to electric arc furnace technology, signaling broader shifts toward lower-emission manufacturing, though not without economic or social strain.

Port Talbot remains an important logistical centre. Its deep-water harbour, capable of handling cape-sized vessels, supports bulk cargo operations. The M4 corridor provides strong road connectivity. While steel still plays a role, the town faces challenges in diversifying its economy amid deindustrialisation. Tourism also contributes modestly. Its coastline, Margam Country Park, and the dramatic industrial landscape attract visitors interested in heritage and scenery.

Cultural and architectural landmarks in Port Talbot include Margam Castle, an 1830s Gothic mansion built for C.R.M. Talbot, and now part of Margam Country Park. The ruins of Margam Abbey and the Margam Stones Museum preserve early Christian carved stones. St. Catharine's Church, Baglan, is home to early medieval cross-slabs. However, its most recognisable features are its industrial skyline, especially the steelworks.
