Carmarthen has a number of surviving heritage attractions including the Roman amphitheatre and medieval castle. The Gwili Railway, a section of the former railway line to Aberystwyth, has been re-opened as a heritage railway for tourists.
Carmarthen has a large proportion of Welsh speakers, with the county of Carmarthenshire as a whole having the largest population of such by number (the largest Welsh-speaking population by proportion is in Gwynedd). Although Carmarthen is on navigable water the harbour no longer sees commercial use, in part due to the treacherous approaches. Carmarthen is location of the headquarters of Dyfed-Powys Police, home to Trinity College Carmarthen - an associate higher education provider of the University of Wales as well as the West Wales General Hospital.
History
Early history
When Britannia was a Roman province, Carmarthen was the civitas capital of the Demetae tribe, known as Moridunum (meaning sea fort). Carmarthen is possibly the oldest town in Wales and was recorded by Ptolemy and in the Antonine Itinerary. The Roman fort is believed to date from AD75-77. A coin hoard of Roman currency was found nearby in 2006. Near the fort is one of seven surviving Roman amphitheatres in the United Kingdom and one of only two in Roman Wales (the other being at Isca Augusta or Roman Caerleon). It was excavated in 1968. The arena itself is 46 by 27 meters; the circumference of the cavea seating area is 92 by 67 meters.
The strategic importance of Carmarthen was such that the Norman William fitz Baldwin built a castle probably around 1094. The existing castle site is known to have been used since 1105. The castle was destroyed by Llywelyn the Great in 1215. In 1223 the castle was rebuilt and permission was received to wall the town and crenellate (a murage). Carmarthen was among the first medieval walled towns in Wales. In 1405 the town was taken and the castle was sacked by Owain Glyndŵr. The famous Black Book of Carmarthen, written around 1250, is associated with the town's Priory of St John the Evangelist and Teulyddog.
During the Black Death of 1347-49 the plague was brought to Carmarthen via the thriving river trade[1]. The Black death 'destroy'd' and devastated villages such as Llanllwch. Local historians place the plague pit, the site for mass burial of the dead, to be the graveyard that adjoins the 'Maes-yr-Ysgol' and 'Llys Model' housing at the rear of St Catherine Street.
