Haverfordwest, United Kingdom

Scores of Iron Age and Roman coinage and artefact discoveries, and excavations by the Dyfed Archaeological Trust under the direction of Heather James at Carmarthen (Moridunum) in the 1980s, point to significant Roman penetration to this westernmost part of Wales. The strategic position of Haverfordwest with its defensive bluff overlooking the lowest fordable point on the western Cleddau and accessible to sea traffic would have required a Roman presence, probably modest in scale, from the 1st century AD to protect supplies to and from the coast, e.g. the Roman legionary headquarters at Caerleon were roofed with slates from the lower slopes of the Preseli Hills. In 1992, aerial photography identified a Roman road running to the west of Carmarthen, past Wiston to Poyston Cross, raising the possibility of Roman fortlets at strategic river crossings at Whitland and Haverfordwest. Edward Llwyd's note to Camden's Britannia (ed. 1695) refers to a valuable find of silver coins at Llanboidy, the latest coin being one of Domitian struck in AD 91. In the 1920s Sir Mortimer Wheeler partially excavated a Roman dwelling or villa at Wolfscastle; work was restarted in 2002 by Professor Merroney. James Phillips, in The History of Pembrokeshire (published 1909), records a find of Roman silver coins in Haverfordwest, the earliest dated coin a Valerian and the latest a Claudius Gothicus. The museum in which the coins were deposited has been "scattered to the winds" and the whereabouts of the coins is unknown.

Phillips claimed that the pre-Norman name of Haverfordwest was Caer Alun, so named by the Emperor Maximus (Macsim Gwledig). His sources are not given but the Cambro-Briton in 1822 also recorded that Maximus, the last Roman Emperor of Britain, a man who for a time divided the Roman Empire with Theodosius I, on withdrawing Roman legions from Britain granted civic status and Celtic names to a number of pacified Romano-British settlements, including Southampton, Chichester, Old Sarum near Salisbury, Carmarthen (Caerfyrddin) and Haverfordwest (Caer Alun). Maximus had married Elen, a Welsh noblewoman, and they had three sons. Phillips claims that the name actually given to the town was Caer Elen, in honour of his wife (the name later changing to Caer Alun).

The ecclesiastical centre of the area (perhaps the seat of a bishop in the Age of the Saints) was probably one of the several churches of the local St Ismael, most probably St. Ishmael's. This occurred around 1110.

The proposition that Haverfordwest Castle was founded by Tancred, a Flemish Marcher Lord, is questionable. The castle is recorded as having been founded in 1100 by the Norman Gilbert de Clare. The Flemings, said to have arrived in three groups in 1107, 1111 and 1151, are likely to have participated in its later development for their own and the Normans' protection from the Welsh warlords. It is recorded that the Constable of the castle in 1207 was Itohert, son of Richard Tancard, possibly a descendant of the first Tancred.

The Flemish presence, reputed to result from floods in the Low Countries, was more likely to have consisted initially of Flemish mercenaries originally in the invading army of William the Conqueror, who in reward for their part in William's victory were granted lands in parts of Northern Britain, and in Wales in the Gower, and Geraldus Cambrensis recorded their presence in the Hundred of Roose in Pembrokeshire.

A Fleming, Wizo, who died in 1130 founded at Wiston a motte and bailey fortification, the forerunner of the stone castle, for protection against the Welsh warlords: the Flemings were reportedly unpopular wherever they settled. The precarious position of Normans and Flemings was demonstrated in 1136 when the Normans, having already lost 500 men in battle at Loughor, re-recruited from Lordships from all over South Wales and led by Robert fitz Martin at Crug Mawr near Cardigan attacked Owain Gwynedd and his army. Routed, they fled over the Teifi Bridge which collapsed; the retreating Normans drowning under the weight of their armour. Their leader Richard de Clare had previously been intercepted and killed by Iorwerth ab Owen. Wiston and the castle were overrun in 1147 by Hywel Sais, son of Lord Rhys. Ranulf Higden, in his Polychronicus, records the Flemings as extinct in Pembrokeshire by 1327 but Flemish mercenaries reappear in 1400 when at the behest of Henry IV they joined an army of 1,500 English settlers who marched north from Pembrokeshire to attack the army of Owain Glyndŵr at Mynydd Hyddgen. The attack was repulsed with heavy casualties and legend has it that English prisoners were spared but surviving Flemish mercenaries were massacred or sold into slavery.

St Mary's Church originated at the end of the 12th century and the current (Grade I listed) building was constructed between the 13th and 15th centuries and prominently visible at the top of the High Street.
