The History of Kidwelly Castle

Kidwelly Castle is a fortress that has witnessed centuries of conflict, rebellion, and transformation. Its story is deeply intertwined with the Norman conquest of Wales, Welsh uprisings, and the evolving political landscape of medieval Britain. From its early wooden origins to its imposing stone structure, the castle’s history reflects the struggles for power and identity in Wales.

The Norman Origins (Early 12th Century)

The origins of Kidwelly Castle date back to 1106 when the Normans sought to consolidate their control over southwest Wales. Roger, Bishop of Salisbury, a trusted advisor to King Henry I, was responsible for constructing the first version of the castle.

• Early Design: The original structure was a motte-and-bailey castle, a common Norman design. A wooden keep sat atop a large earth mound (motte), while a surrounding courtyard (bailey) housed barracks and storage buildings.
• Strategic Location: Kidwelly Castle’s position beside the River Gwendraeth gave it a natural defensive advantage. It also allowed the Normans to control trade routes and monitor the surrounding Carmarthenshire region.

The Normans built the castle to secure their hold over the area, which was frequently contested by the native Welsh rulers.

The Rebellion of Gwenllian ferch Gruffydd (1136)

In 1136, Kidwelly Castle became the focal point of a dramatic and tragic chapter in Welsh history.

• Gwenllian ferch Gruffydd, a Welsh princess and the wife of Gruffydd ap Rhys, led a rebellion against the Normans. While her husband rallied support elsewhere, Gwenllian gathered local forces to attack Kidwelly Castle.
• The Battle: Gwenllian and her forces launched a daring assault on the castle. However, the Normans repelled the attack, and Gwenllian was captured. She was executed near the castle, a fate that turned her into a symbol of Welsh resistance.
• Legacy: Gwenllian’s bravery is remembered as an inspiration for future generations. A nearby field, “Maes Gwenllian,” is named in her honor, commemorating her sacrifice.

The rebellion highlighted the ongoing tensions between the native Welsh rulers and the Norman occupiers.

The Transition to Stone (Late 12th–13th Century)

By the late 12th century, the Normans recognized the need for stronger defenses. The de Chaworth family, who held the castle at the time, began rebuilding it in stone.

• Stone Fortifications: The wooden structures were replaced with thick stone curtain walls, round towers, and a fortified gatehouse.
• Symbol of Power: The transformation of Kidwelly Castle into a stone fortress reflected the Normans’ growing dominance and their determination to maintain control over Carmarthenshire.

The new stone castle became a formidable stronghold, able to withstand prolonged sieges and attacks.

The De Bohun Era and Further Fortifications (14th Century)

During the 14th century, the castle passed into the hands of the de Bohun family, powerful Marcher lords who further reinforced its defenses.

• Gatehouse Construction: The de Bohuns added the castle’s iconic gatehouse, which included a portcullis, murder holes, and flanking towers. This made the castle’s entrance nearly impenetrable.
• Curtain Wall Enhancements: The curtain walls were strengthened, and additional defensive features, such as arrow slits and battlements, were incorporated.
• Domestic Improvements: The castle’s inner ward was expanded to include more comfortable living quarters, reflecting the growing importance of residential spaces within fortifications.

The de Bohun family’s contributions solidified Kidwelly Castle’s reputation as one of the strongest and most well-designed fortresses in Wales.

The Glyndŵr Rebellion (15th Century)

In the early 15th century, Wales erupted in rebellion under the leadership of Owain Glyndŵr, the last native Prince of Wales. His campaign aimed to overthrow English rule and restore Welsh independence.

• Strategic Importance: Kidwelly Castle remained a vital stronghold during this period. Its strong defenses helped it withstand the chaos of the rebellion.
• Aftermath: Though Glyndŵr’s uprising ultimately failed, the conflict marked one of the last significant challenges to English dominance in Wales.

Kidwelly Castle’s survival during this turbulent period demonstrated its enduring strength and strategic value.

Decline and Disrepair (16th–17th Century)

By the 16th century, Kidwelly Castle’s military importance began to decline.

• Changing Warfare: Advances in artillery and siege technology made traditional castles less effective as defensive structures.
• Neglect: The castle was no longer maintained as a military fortress. Over time, its walls began to crumble, and parts of the structure fell into ruin.
• Symbolic Role: Despite its decline, Kidwelly Castle remained a symbol of Norman power and Wales’s rich history.

During the English Civil War in the 17th century, the castle saw limited action. Its already deteriorating condition meant it played little role in the conflict.

Romantic Rediscovery and Preservation (19th–20th Century)

In the 19th century, Kidwelly Castle became a subject of fascination during the Romantic era.

• Artists and Writers: Painters and poets admired the castle’s dramatic ruins and picturesque riverside setting. Its rugged beauty inspired works that celebrated Wales’s medieval past.
• Preservation Efforts: By the 20th century, efforts to preserve Kidwelly Castle began in earnest. The site was stabilized, and its historical significance was recognized.

Today, the castle is managed by Cadw, Wales’s historic environment service. Visitors can explore its ruins, climb its towers, and immerse themselves in its fascinating history.

The Architecture of Kidwelly Castle

Kidwelly Castle stands as one of the most impressive and well-preserved examples of Norman and later medieval military architecture in Wales. Built and expanded over several centuries, its design reflects the changing needs of defense, power projection, and domestic life. From its massive curtain walls to its fortified gatehouse, Kidwelly Castle embodies the evolution of medieval fortress construction.

The Early Norman Structure: Motte-and-Bailey Beginnings

The original Kidwelly Castle, built around 1106 by Roger, Bishop of Salisbury, was a classic motte-and-bailey design.

• The Motte: A large, artificial mound of earth formed the base for a wooden keep. This high position gave defenders a significant advantage during attacks.
• The Bailey: A courtyard at the base of the motte housed wooden buildings such as barracks, stables, and storage facilities.
• Wooden Palisade: A timber palisade surrounded the motte and bailey, offering protection against enemy assaults.

This early design allowed the Normans to establish a strong presence quickly. However, wooden structures were vulnerable to fire and decay, which led to their replacement with stone fortifications.

The Transition to Stone: 12th–13th Century Developments

By the late 12th century, Kidwelly Castle was rebuilt in stone under the ownership of the de Chaworth family. This marked a major shift in its architectural design, transforming it into a more formidable and permanent fortress.

• Stone Curtain Walls: Thick, high stone walls replaced the wooden palisade. These walls enclosed the inner and outer wards, providing stronger defenses.
• Round Towers: Four imposing round towers were added to reinforce the curtain walls. Their circular design helped deflect projectiles and prevented attackers from undermining the walls.
• Inner Ward: The inner ward contained essential structures such as the Great Hall, living quarters, and kitchens. These spaces combined functionality with comfort for the castle’s lord and his family.

The use of locally quarried stone ensured the castle’s durability while blending it seamlessly with the surrounding landscape.

The Magnificent Gatehouse: 14th Century Fortification

The gatehouse is one of Kidwelly Castle’s most striking architectural features. Built in the 14th century under the de Bohun family, it reflects the growing importance of controlled access and layered defense.

• Portcullis and Drawbridge: The gatehouse featured a heavy portcullis and a drawbridge, creating a formidable barrier against attackers.
• Murder Holes: Openings in the ceiling above the entrance allowed defenders to drop boiling water, stones, or other projectiles on intruders.
• Arrow Slits: Narrow arrow slits on either side of the entrance enabled archers to fire on enemies while remaining protected.
• Defensive Towers: Two strong, semi-circular towers flanked the gatehouse, providing additional protection and serving as lookout points.

The gatehouse’s design highlights the castle’s focus on defense while also serving as a powerful symbol of the lord’s authority.

The Inner Ward: A Blend of Defense and Domestic Life

The inner ward of Kidwelly Castle was the heart of the fortress, combining military strength with residential functionality.

• The Great Hall: This large, central building served as the main gathering space for feasts, meetings, and administrative duties. Its high ceilings, fireplaces, and large windows reflected the importance of comfort and status.
• Private Chambers: The lord’s private quarters featured fireplaces and narrow windows, balancing warmth and security.
• Kitchens and Storage: The inner ward included kitchens, pantries, and storerooms to support the castle’s occupants during peacetime and sieges.

The inner ward’s layout demonstrated the castle’s dual role as both a military fortress and a noble residence.

The Curtain Walls and Defensive Towers

The castle’s curtain walls are among its most impressive features, encircling the entire site and providing formidable protection.

• Massive Stone Walls: The walls were built with thick stone blocks, making them resistant to siege weapons like battering rams and catapults.
• Defensive Walkways: Guard patrols used stone walkways along the tops of the walls to monitor the surrounding area and repel attackers.
• Round Towers: Four strong, round towers were strategically placed along the curtain walls. Their curved design reduced weak points and allowed defenders to fire in multiple directions.

The curtain walls and towers created an unbroken line of defense, making the castle nearly impenetrable during its prime.

The Outer Ward and River Defenses

Kidwelly Castle’s outer ward provided additional protection and space for essential activities.

• Outer Defenses: The outer ward included additional walls and a ditch to slow down advancing enemies.
• River Gwendraeth: The castle’s position beside the River Gwendraeth added a natural barrier on one side. This made it difficult for attackers to approach without being seen or slowed.

The combination of man-made and natural defenses ensured that Kidwelly Castle remained a stronghold for centuries.

Restoration and Preservation

By the 16th century, Kidwelly Castle’s military importance had declined. It gradually fell into ruin, but its robust stone structures ensured that much of it survived.

In the 20th century, efforts to preserve the castle began. Today, it is managed by Cadw, Wales’s historic environment service. Restoration work has stabilized the ruins, allowing visitors to explore its architectural marvels safely.
