Neath is a historic market town in Neath Port Talbot, set on the River Neath, roughly seven miles northeast of Swansea.

Its position at the lowest crossing point of the river has shaped its identity for more than two millennia, making it a place where ancient settlement, medieval power, and industrial transformation meet.

Archaeological evidence shows that the Neath area was significant long before written history. Several Celtic hillforts overlook the valley, indicating organised settlement and strategic use of the landscape. The Romans recognised this same strategic value and around AD 74 built the auxiliary for Nidum on the western bank of the River Neath. Excavations have revealed stone walls, gate towers, and even a large marching camp capable of housing thousands of soldiers, unusual features that highlight the intensity of Roman military activity against the Silures.

Nidum appears in the Antonine Itinerary, confirming its importance within Roman Wales. The fort was intermittently occupied until the early 4th century, leaving a deep imprint on the town's origins.

The English name Neath derives from the Welsh Nedd, the ancient name of the river. Linguists suggest a Celtic or even pre-Celtic root meaning "shining" or "brilliant," or possibly an Indo-European root simply meaning "river." The Welsh name Castell-nedd (castle on the Nedd) reflects the medieval fortress that later dominated the town.

After the Roman withdrawal, the area remained a focal point of settlement. Saint Illtyd established an early Christian community at what is now Llantwit, and the church that bears his name still incorporates Norman and pre-Norman fabric.

In the 12th century, the Normans consolidated their control by building Neath Castle, visited by kings including Henry II, John, and Edward I. Around the same period, in 1130, Richard de Glanville founded Neath Abbey, which grew into one of Wales' most important Cistercian monasteries. The abbey's influence shaped the emerging town and market, though the settlement suffered repeated attacks from the Welsh lords of Afan before stabilising into a walled town by the 14th century.

Neath was an early participant in Wales' industrial revolution. By the 16th century, coal mining and copper smelting were already established. The 18th and 19th centuries brought rapid expansion: ironworks, tinplate production, and extensive canal building - including the Neath Canal (1795) and the Swansea-Aberdulais Canal (1824) - which linked the town to ports and inland industrial sites.

The arrival of two railways in 1850-1851 cemented Neath's role as a major industrial hub. Victorian travellers described the valley as a dramatic contrast of natural beauty and fiery industrial spectacle, with abbey ruins at one end and blazing furnaces at the other.

Today, Neath forms part of a wider industrial region that includes steel, petrochemicals, and manufacturing, though the town itself has diversified into commercial and residential functions within the Neath Port Talbot area.

Significant places within Neath include Neath Abbey. Among the largest monastic ruins in Wales, its Cistercian architecture and atmospheric remains make it a key heritage attraction. Neath Castle is a Norman fortress whose surviving gatehouse and walls evoke the medieval power struggles of the region. St. Illtyd's Church is a rare example of a church retaining both pre-Norman and Norman elements, reflecting centuries of continuous worship. Although largely buried beneath modern development, excavated sections of the Roman Fort of Nidum can be seen near Dŵr‑y‑Felin Road. Once a vital industrial artery, Neath Canal is now a scenic route for walking and wildlife.
