About
Berkhamsted Castle is a Norman motte-and-bailey fortress occupying a commanding position in the Hertfordshire market town of Berkhamsted, and one of the most historically significant castle sites in England. Founded in the immediate aftermath of the Norman Conquest of 1066, it was at Berkhamsted that Edgar Atheling — the last Anglo-Saxon claimant to the English throne — led the English nobles, archbishops, and surviving Saxon magnates in their formal submission to William the Conqueror, effectively ending Anglo-Saxon resistance and sealing the Norman conquest of England. This single act of political capitulation, made within weeks of the Battle of Hastings, gave Berkhamsted Castle a place at the very pivot point of English history.
William granted the castle to his half-brother Robert of Mortain, and it quickly grew into one of the most important royal strongholds in the kingdom. Successive Norman and Plantagenet kings enlarged and embellished the fortification, adding a stone shell keep atop the motte, a great hall, towers, and an elaborate double ditch and counterscarp bank that remains one of the finest surviving examples of Norman defensive earthworks in Britain. The castle passed through some of the most celebrated hands in medieval English history: Thomas Becket served as its constable under King Henry II before his elevation to Archbishop of Canterbury; Geoffrey Chaucer held the position of clerk of works here; and Edward the Black Prince, eldest son of Edward III and one of the greatest military commanders of the age, used Berkhamsted as his principal residence and favourite retreat for much of his life.
The castle was periodically remodelled and extended through the 13th and 14th centuries, at its height encompassing a substantial outer bailey with additional towers and water defences fed by the River Bulbourne. By the Tudor period it had fallen from royal favour and gradually decayed, passing eventually into private hands before coming under state guardianship. Today English Heritage cares for the remains, which survive in exceptionally good condition: the great motte rises prominently from its double moat system, sections of flint curtain wall and tower bases trace the former circuit of the castle, and the earthworks convey the full extent and ambition of what was once a major royal fortress. The site sits immediately beside Berkhamsted railway station, making it one of the most accessible English Heritage sites in the south of England. Entry is free at all times.

💡 Visitor Tips
- Arrive by train from London Euston (35 minutes) — the castle is a 2-minute walk from the station exit, making this one of the easiest English Heritage sites to reach without a car.
- Climb the motte for panoramic views across Berkhamsted and the surrounding Hertfordshire countryside — the path is grassy and can be slippery after rain.
- Allow time to walk the full circuit of the outer ditch to appreciate the true scale of the defensive earthworks from all angles.
- Visit on a weekday morning for the most peaceful experience — the site is popular with local dog walkers and families at weekends.
- Combine with a walk along the Grand Union Canal towpath (5 minutes south of the castle) for a pleasant half-day in the area.
- Explore Berkhamsted High Street after your visit — it has a well-preserved historic core with good cafes, bakeries, and independent shops.
- Wear sturdy footwear — the earthworks are uneven grass and can be muddy in wet weather, particularly around the ditch circuits.
- No facilities are on site, so bring water and snacks, especially if visiting with children.
Highlights
The Great Motte — Heart of the Norman Stronghold
The castle's most dramatic feature is its great motte — a massive conical earthen mound rising approximately 15 metres above the surrounding ground level. This was the foundation of the original Norman timber tower, later replaced by a stone shell keep, and it served as the ultimate refuge and command point of the fortress.
From the summit, which visitors can climb on a grass path, the views across Berkhamsted and the surrounding Hertfordshire countryside are extensive.
The sheer scale of the motte, still imposing after nearly a thousand years, communicates the power and ambition of the Norman lords who commissioned it. The mound's silhouette against the sky remains one of the most evocative Norman earthwork profiles in southern England.
The 1066 Submission — Where England's Fate Was Decided
Few sites in England can match Berkhamsted's claim to historical importance. It was here, in the weeks following the Battle of Hastings in October 1066, that Edgar Atheling, the last Anglo-Saxon claimant to the English throne, led the surviving English nobility — including the Archbishops of Canterbury and York, and the great ealdormen of the kingdom — in formal submission to William the Conqueror.
This act of capitulation sealed the Norman Conquest and redirected the entire course of English history, language, law, and culture.
Walking the grounds of Berkhamsted Castle, one stands where England changed hands. No plaque fully conveys the magnitude of what was decided on this very soil.
The Double Ditch and Counterscarp Bank
Berkhamsted preserves one of the most complete and impressive double ditch defensive systems of any Norman castle in England. Two deep moats encircle the motte and inner bailey, separated by a substantial counterscarp bank — a configuration providing exceptional defensive depth. The outer ditch was originally water-filled, fed by the nearby River Bulbourne, creating a wide, wet barrier that made direct assault extremely difficult.
Today the ditches are dry but their dimensions remain formidable: they are broad and deep enough to be clearly read as military earthworks of serious intent. Walking around the castle perimeter, the sequential barriers of moat, bank, and motte create a vivid impression of the layered defensive thinking of Norman military engineers.
Thomas Becket's Constableship
Among the many distinguished figures associated with Berkhamsted Castle, Thomas Becket — later Archbishop of Canterbury and martyr — stands out as particularly resonant. Becket served as constable of the castle under King Henry II, responsible for its administration and military readiness during one of the most politically charged periods of its history.
His time at Berkhamsted preceded his transformation from royal favourite and Lord Chancellor to implacable opponent of the Crown over the rights of the English Church.
The castle thus witnessed the early career of one of medieval England's most celebrated and controversial figures, and its stones are bound up with the beginning of Becket's extraordinary trajectory from royal servant to saint.
Collections
Berkhamsted Castle is an open-air archaeological monument rather than a museum, and there are no permanent display collections on site. The monument itself — comprising the great motte, double ditch system, curtain wall remains, tower bases, and outer bailey earthworks — constitutes the primary resource for understanding this important site.
Interpretive panels at the entrance provide contextual information about the castle's Norman origins, its royal history, and the key figures associated with it.
English Heritage's website and guidebooks offer detailed accounts of the archaeological investigations and historical records. The main finds from past excavations are held in regional museum collections; however, the castle's real collection is the landscape itself, which has been remarkably well preserved and provides a compelling physical record of nearly a thousand years of Norman and medieval history.
