Haverfordwest Castle

Haverfordwest Castle stands prominently in the town centre of Haverfordwest, Pembrokeshire, South Wales, occupying a naturally defensive position on a strong, isolated ridge. This high medieval hill castle was originally established around 1120 during the Norman expansion into West Wales. Although the site is traditionally believed to have hosted an Iron Age hill fort, no physical remains confirm this earlier occupation. The castle's location was strategically chosen to control the surrounding area and protect Norman interests against Welsh incursions.

The castle's history is entwined with the complex political landscape of medieval Wales. Before the Norman conquest of West Wales in 1093/94, the area was thought to be a Danish settlement. Following the conquest, the Normans settled Flemish colonists in the region around 1108 to safeguard the main Norman stronghold at Pembroke Castle from northern Welsh raids. Haverfordwest Castle was constructed as part of this defensive network, with much of its surviving architecture dating from the late 13th century, notably the extensive curtain walls built around 1290.

Medieval origins and strategic importance

The castle's initial construction likely featured a typical Norman motte-and-bailey design, evolving over time into a more complex stone fortress. The surviving curtain walls and towers reflect the architectural advancements of the high medieval period. The castle served as a vital royal stronghold for centuries, with ownership passing to the English crown between 1381 and 1385. During this time, significant restoration work was undertaken to strengthen its defenses.

These improvements proved crucial during the Welsh uprising led by Owain Glyndŵr in the early 15th century. In 1405, the castle successfully withstood an attack, demonstrating the effectiveness of its fortifications. The surrounding town walls, although now lost, also contributed to the castle's defense by protecting the high ground around the fortress.

Architectural features and layout

Haverfordwest Castle showcases a combination of round and square towers positioned at strategic points along the curtain walls. The north-west and south-west corners are defended by round towers, while the south-east corner features a distinctive square tower with an additional projecting turret. The south-west and south-east towers rise to three storeys, with the south-east tower containing a basement and a postern gate that could be used for counter-attacks during sieges.

The castle's great hall is located on the southern side, notable for its large, high windows and features that include scaling ladders, indicative of its defensive as well as residential function. The outer ward retains little of its original medieval defenses, but the curtain wall remains largely intact along the north side, including a semicircular turret and a square tower to the east.

Castle entrance and defensive structures

The original main entrance was on the west side, protected by a gatehouse, though no physical traces of this survive today. The castle's design reflects the military architecture of the late 13th century, emphasizing strong curtain walls and strategically placed towers to maximize defense against attackers.

Later history and use

By the 16th century, Haverfordwest Castle had fallen into disrepair. It was re-fortified during the English Civil War, with records from 1644 indicating that the castle was occupied by Royalist forces. Interestingly, the Royalists abandoned the castle after mistaking the sounds of cows for an approaching Parliamentary army. The castle was subsequently recaptured and held for the king until surrendering following the nearby Battle of Colby Moor.

In 1648, Oliver Cromwell ordered the castle's destruction, threatening imprisonment for the townsfolk if they failed to comply. Letters bearing these orders were discovered in 1986 and are now displayed in the local museum, providing a direct link to this turbulent period.

Conversion to prison

In the late 18th century, the castle was repurposed as a prison, with a new prison building constructed within the inner bailey in 1820. This adaptive reuse reflects the changing needs and functions of the site over time. Today, the castle is managed by the Pembrokeshire Coast National Park Authority and is accessible to the public as a historical monument.

Regional context and related sites

Haverfordwest Castle is part of a network of medieval fortifications in Pembrokeshire. Nearby castles include Wiston Castle, located approximately 6 miles to the northeast, and the prominent Pembroke Castle, about 12 miles to the south. These castles collectively illustrate the strategic importance of the region during the Norman and medieval periods.

The castle's enduring presence in the town centre and its extensive medieval fabric make it a significant heritage site, offering insights into the military, political, and social history of South Wales.
