Roman archaeology, medieval castle remains, walking routes and a historic market offer different ways to explore Carmarthen. The amphitheatre is considered the westernmost in the entire Roman Empire, while Carmarthen Castle, with its surviving structures and views over the Tywi, offers a different historical focus. Memorial plaques in the town centre and local produce at the market are also among the features that shape the town.

Roman heritage and the castle by the Tywi

Carmarthen’s Roman amphitheatre was built on a hillside. Together with its position as the westernmost amphitheatre in the entire Roman Empire, this offers a distinctive way into Roman history: its significance is clear both from its place in the Empire and from its specific hillside setting. This connection between historical reach and location on a slope is particularly interesting for travellers interested in archaeology.

Carmarthen Castle stands on a rocky hill with views over the River Tywi. Its surviving features include a stone-faced motte, visible semicircular corner towers, a largely rebuilt curtain wall and a 14th-century gatehouse. By around 1105, the Norman castle already stood at the present site of Carmarthen Castle. The castle therefore offers a different historical focus from the amphitheatre: its surviving structures, views over the Tywi and Norman history shape its character.

Exploring the town’s history on foot

The Carmarthen Blue Plaque Trail was introduced in 2025 as a free, self-guided walk through the town centre. It visits memorial plaques on significant buildings and at notable sights. Confirm locally that it is currently available before your visit.

The Carmarthen Town Walk passes through the historic town and along the River Tywi. The two routes have different focuses: the Blue Plaque Trail centres on individual memorial plaques, while the Town Walk includes the historic town and river in its route. This distinction can help you choose a walk: would you prefer to focus on memorial plaques or follow a route that takes in the town’s history and the river?

The market and coracle-fishing tradition

Carmarthen’s market has existed for more than 800 years and dates back to Roman times. Stalls at the market sell locally produced meat, fruit and vegetables, cheese and cakes. Alongside its historic sites, the market offers another way to experience Carmarthen, with food and locally produced goods taking centre stage. The different categories of goods provide a tangible point of interest for travellers who would like to include regional produce in their explorations as well as cultural attractions.

Another historic tradition is fishing with coracles on the Tywi. It has been practised in Carmarthen since before the Romans arrived; today, only a few coracle fishermen remain active. This long tradition and the small number of active fishers make it a distinctive cultural counterpoint to the amphitheatre and castle. Together, these different focal points show that Carmarthen’s history is expressed not only in historic buildings but also in a river tradition that is still practised today.
