Raglan Castle

Raglan Castle: Where Henry Tudor Was Raised, Among Wales's Grandest Ruins

Before Henry Tudor became King Henry VII of England — before he won the Battle of Bosworth in 1485 and founded the Tudor dynasty that would rule Britain for 118 years — he was a boy living at Raglan Castle in Monmouthshire.

Taken as a ward by William Herbert after his father's death, he grew up here in the 1460s, in a castle that was then one of the most magnificent in Wales, under the care of a man who had helped to win the Wars of the Roses for the House of York. That Herbert was executed in 1469, and that Henry later took the throne he had once lived in sight of, is one of the more extraordinary reversals in the castle's extraordinary history.

Raglan Castle was begun in the 1430s by Sir William ap Thomas — the "Blue Knight of Gwent," a veteran of Agincourt — who raised the hexagonal Great Tower that still dominates the ruins today. His son William Herbert completed and embellished it into a fortress-palace of European ambition. The Somerset family later added Renaissance gardens among the finest in Britain.

It was a Royalist stronghold through the longest Civil War siege in Wales. It was slighted by Parliamentary forces in 1646, its Great Tower too solid to demolish entirely. It has been a romantic ruin ever since, and it is managed today by Cadw as one of the finest late medieval castle ruins in Wales. This guide covers everything you need to plan your visit.

Where Is Raglan Castle?

Raglan Castle is in the village of Raglan, Monmouthshire, South Wales, approximately 7 miles south-west of Monmouth off the A40. From Cardiff, allow around 45 minutes by car; from Bristol around an hour. Free parking for around 120 cars is available within the castle grounds.

By public transport, bus route 60 between Newport and Monmouth stops in Raglan village, a ten-minute walk from the castle. Abergavenny station, 9 miles away, is the nearest rail connection, with services to Cardiff, Bristol and London.

A Brief History of Raglan Castle

Sir William ap Thomas — known as the Blue Knight of Gwent for the colour of his battle armour — fought at the Battle of Agincourt in 1415 and returned to Wales one of the most celebrated soldiers of his generation. In the 1430s, he began construction of the Great Tower at Raglan: a five-storey hexagonal keep surrounded by its own moat, separate from the castle's main defences and accessible only by drawbridge — a tower that was both the most formidable defensive element of the building and a symbol of his status.

When William ap Thomas died in 1445, his son William Herbert inherited and transformed Raglan into something far grander. Herbert was one of the most powerful figures in the Wars of the Roses, fighting for the House of York and accumulating titles and estates accordingly. Edward IV created him Earl of Pembroke in 1468 in recognition of his capture of Harlech Castle.

Henry Tudor — the future Henry VII — was raised at Raglan as Herbert's ward from around 1461 until Herbert was executed in 1469, a victim of the same dynastic turbulence he had helped to create. That the boy who grew up in this castle became the king who ended the Wars of the Roses is one of history's more satisfying ironies.

The castle passed to the Somerset family in 1492, who added the long gallery, the elaborate gatehouse and the Renaissance gardens for which Raglan is now particularly valued. During the English Civil War, it was a Royalist stronghold, held by a garrison of around 800 men through a siege by Parliamentary forces under Sir Thomas Fairfax that lasted several months in 1646 — the longest Civil War siege in Wales. The castle fell, was slighted, and the Somersets chose not to restore it after the Stuart Restoration. Raglan entered its long life as a ruin.

The remarkable thing about Raglan is the completeness of its architectural ambition. This was not purely a military fortress but a fortress-palace that aspired to the standards of the finest European residences of its day: Renaissance gardens, elegant great halls, long galleries for courtly promenading. The ruins of that ambition are among the most impressive in Wales.

Architecture & Design

The Great Tower — or Yellow Tower of Gwent — is Raglan's defining structure: a five-storey hexagonal keep surrounded by its own water-filled moat, originally accessible only by a drawbridge from the main castle. Even substantially damaged by the 1646 slighting, it stands as the most impressive surviving tower at any castle in south-east Wales, its hexagonal plan unique in the region. The walls bear the marks of the Parliamentary artillery — visible evidence of the siege — and the demolition attempts that failed to bring it down entirely.

The ornate gatehouse, built by William Herbert, features dramatic flared machicolations — the projecting stone arches from which missiles could be dropped on attackers. The Fountain Court and Pitched Stone Court give a sense of the castle's palatial scale. The hall's oriel window reflects the shift from purely defensive to residential aspirations. And the terraced Renaissance gardens — with their water parterre, knot garden structure and terraced levels — are among the most significant garden survivals from the period in Britain, even in their ruined state.

The visitor centre displays remarkable survivals, including a piece of Tudor wooden panelling recovered from a local cow shed in the 1950s — evidence of how the castle's fabric dispersed after the slighting, repurposed in unexpected places.

Legends & Lore

Raglan Castle has no established ghost tradition — the weight of documented history here is too substantial to require any embellishment. The Blue Knight's Agincourt campaign and his hexagonal tower; Henry Tudor's childhood in these courtyards; the Wars of the Roses unfolding through the lives of the Herberts; the months-long siege of 1646 and the Parliamentary soldiers failing to demolish the Great Tower — these stories are embedded in the surviving fabric of the building.

The fish in the moat around the Great Tower are perhaps the gentlest detail in a castle of considerable drama: successive generations of fish swimming where the drawbridge once crossed, the moat serving no military purpose for nearly four centuries and yet still functioning as a moat.

Visiting the Castle

Raglan Castle is managed by Cadw and is open year-round, with longer hours in summer and shorter in winter. Cadw members enter free. The visit is self-guided through the ruins, with the visitor centre providing an introduction to the history and the Tudor panelling.

The Great Tower and its moat are the focal point of the visit — walking around the hexagonal keep, seeing the artillery damage from the 1646 siege and looking up at the remaining fabric of the five storeys gives the most direct sense of the castle's ambition and its dramatic end. The gatehouse's machicolations are among the finest surviving examples in Wales. The Fountain Court and the remnants of the Renaissance gardens reward careful attention — the terraced structure, the water channel lines and the knot garden foundations are readable even in ruin.

A nearby café in a converted farm stable block is a short walk from the castle and serves fresh food with views of the Monmouthshire countryside. Photography is permitted for personal use throughout the castle. Dogs are welcome in the outdoor areas.

The Best Time to Visit

Spring (April to June) is excellent at Raglan — the Monmouthshire countryside is vivid green, the castle grounds are at their best and visitor numbers are lower than in peak summer. Summer (July to August) brings the longest opening hours and the best weather; the Fountain Court and garden terraces are at their most readable. Autumn (September to October) offers the Welsh landscape in autumn colour and significantly quieter visits.

Winter sees shorter hours; the castle in winter light, with the Great Tower standing against a grey Welsh sky, has a dramatic atmosphere of its own.

• Pack a compact travel umbrella; Monmouthshire weather is changeable.
• Bring a portable power bank for photography across the ruins, the Great Tower and the Monmouthshire views.
• Look closely at the Great Tower for the artillery damage from the 1646 siege — the scars are visible in the stonework and tell the story of the failed demolition.

• Overseas visitor? Pack a UK travel adapter for Type G plugs.

Conclusion

Raglan Castle was built by a veteran of Agincourt, completed by a man who raised the future Henry VII, besieged for months by the army that won the English Civil War and left too solid to fully demolish.

The hexagonal Great Tower in its moat — the most individual structure at any Welsh castle ruin — survived everything thrown at it and stands in the Monmouthshire countryside today, its artillery scars still visible, the fish in the moat beneath it undisturbed. It is the grandest ruin in south-east Wales, and one of the finest in Britain.
