About
Caldicot Castle is a substantial and well-preserved medieval fortress set in 55 acres of beautiful country parkland in south-east Wales, close to the Severn estuary and the English border. The castle's origins reach back to the Norman period — the great round keep dates from the twelfth century — and successive phases of construction through the thirteenth and fourteenth centuries produced a complex and visually impressive fortification that remains one of the most complete medieval castles in Monmouthshire.
The castle was built by the de Bohun family, Earls of Hereford and one of the most powerful Norman-Welsh Marcher dynasties, as part of the network of lordships and fortifications that controlled the borderlands between England and Wales. The earliest surviving structure is the imposing round keep, built in the late twelfth century and still standing to its full height, which commands views across the surrounding parkland and countryside. The fourteenth-century gatehouse, with its twin drum towers and portcullis groove, is a particularly fine example of later medieval military architecture and serves as the principal entrance to the castle courtyard.
The castle passed through various hands over the centuries, falling into progressive ruin after the medieval period until its rescue by Joseph Cobb in the mid-nineteenth century. Cobb, a wealthy antiquarian and gentleman, purchased the castle in 1885 and undertook a romantic Victorian restoration that made it habitable as a country house while preserving its medieval character. The great hall and domestic apartments were restored with Victorian Gothic enthusiasm, creating an interior that blends medieval stonework with Victorian craftsmanship. Monmouthshire County Council acquired the castle in 1963 and has maintained it as a heritage attraction and country park since.
The castle's interior houses displays on its history from Norman origins through medieval lordship to Victorian restoration, with artefacts, interpretation panels, and reconstructed medieval rooms that bring the castle's domestic and military life into focus. The surrounding country park, with its mature trees, gardens, and open grassland, provides a peaceful and attractive setting for family visits and community events.
Caldicot Castle hosts a popular programme of events throughout the year, including medieval re-enactments, outdoor theatre, craft fairs, and seasonal celebrations that animate the castle and its grounds with activity. The castle is also a popular venue for weddings and private events, its romantic setting and medieval architecture providing an atmospheric backdrop for celebrations.

Highlights
The Norman Round Keep
The great round keep is the oldest and most imposing structure at Caldicot Castle, dating from the late twelfth century and still standing to its full original height. Built by the de Bohun family as the castle's principal defensive strongpoint, the keep's massive walls and commanding elevation made it the last refuge in time of attack.
The climb to the top of the keep — up a narrow stone spiral staircase worn smooth by centuries of use — is rewarded with panoramic views across the country park, the Severn estuary, and the surrounding Monmouthshire countryside.
The keep's interior retains its medieval character with minimal modern intervention.
The Fourteenth-Century Gatehouse
The gatehouse at Caldicot Castle is one of the finest examples of later medieval castle architecture in south-east Wales, with its twin drum towers flanking a vaulted entrance passage equipped with portcullis groove and murder holes — the classic defensive features that made a medieval gatehouse far more than a simple entrance.
Built in the early fourteenth century to strengthen the castle's defences, the gatehouse combines military functionality with architectural ambition, its proportions and detailing reflecting the status and wealth of its de Bohun builders. The upper chambers of the gatehouse served as high-status accommodation, and their restored interiors are among the most atmospheric spaces in the castle.
The De Bohun Family and the Welsh Marches
Caldicot Castle was built and developed by the de Bohun family, Earls of Hereford and one of the most powerful baronial dynasties of medieval England and Wales. The de Bohuns held vast estates across the Welsh Marches — the volatile borderlands where English and Welsh power intersected — and their castles at Caldicot, Brecon, and elsewhere formed a network of fortifications that projected Norman and English authority into Welsh territory.
The museum displays explore the de Bohun legacy, their role in the great political crises of medieval England, and the daily life of a Marcher lordship where military readiness and estate management were constant preoccupations.
Victorian Restoration by Joseph Cobb
The castle owes its current condition to the passion and investment of Joseph Cobb, a wealthy antiquarian who purchased the ruined castle in 1885 and undertook an extensive programme of restoration in the romantic Victorian Gothic style. Cobb restored the great hall, domestic apartments, and defensive structures with a combination of scholarly interest in medieval architecture and the Victorian enthusiasm for picturesque medievalism that transformed many British castles and country houses during the period.
The restored interiors blend genuine medieval stonework with Victorian craftsmanship, creating spaces that are both historically evocative and architecturally distinctive.
