History
Lewes Castle is a medieval Norman castle in Lewes, United Kingdom, built after the Norman Conquest in the eleventh century as a motte-and-bailey fortress guarding the gap in the South Downs cut by the River Ouse, together with the towns of Lewes and Cliffe. Originally called Bray Castle, it was constructed by William de Warenne, 1st Earl of Surrey, and became an important military and administrative stronghold.
Norman foundation and expansion
The first mound, Brack Mount, was completed shortly after 1066, when William, Duke of Normandy, invaded and took control of England. A second mound, known as the Keep, followed in the late eleventh century. The castle therefore developed around two raised defensive platforms rather than a single motte. Both mottes were initially protected by wooden palisades.
At the beginning of the twelfth century, the wooden defenses were replaced by masonry shell keeps, substantial stone enclosures built on the mottes. Towers were added to one of these shell keeps during the thirteenth century, while a barbican gate, an outer defensive structure protecting an entrance, was added in the fourteenth century.
The Battle of Lewes and the Warenne succession
In 1264, during the conflict that culminated in the Battle of Lewes, soldiers left the castle to join Simon de Montfort, the nobleman leading baronial forces against King Henry III. Henry stayed at the castle before the battle. After the fighting, the king and his son Edward were captured. The battle has been described as contributing to the beginnings of parliamentary monarchy in Britain.
John de Warenne, 7th Earl of Surrey and the last of the de Warennes, died without issue in 1347 and was buried at Lewes Priory, a medieval religious foundation in the town. His title passed to his nephew Richard FitzAlan, 10th Earl of Arundel.
Preservation and modern changes
The Sussex Archaeological Society leased Lewes Castle from 1850. Charles Thomas-Stanford acquired the castle and presented it to the society in 1922, linking the monument’s later history with organized efforts to study and preserve Sussex’s heritage. Lewes Castle was designated a scheduled monument on 28 August 1915.
On 11 November 2019 at 12:22 GMT, a section of curtain wall measuring approximately 10 by 10 metres collapsed onto an adjacent house and garden. The section was privately owned and weighed approximately 600 tonnes. Emergency services found no casualties, and the castle was closed as a precaution. The sections owned by the Sussex Archaeological Society were independently inspected annually.
Remains
Lewes Castle follows a motte-and-bailey plan, combining elevated artificial mounds with a defended enclosed area. It stands on a man-made mount just north of Lewes High Street, in a position overlooking the route through the South Downs formed by the River Ouse. Its two mottes, masonry shell keeps, stone curtain wall, towers, and later entrance defenses preserve the main elements of its medieval arrangement. The castle was built from local limestone and flint blocks.
The two mottes and shell keeps
Brack Mount
Brack Mount is the castle’s first motte, completed shortly after 1066. It was originally topped by a wooden palisade, which was replaced at the beginning of the twelfth century by a masonry shell keep, a substantial stone enclosure built on the mound.
The Keep
The Keep is the second motte, completed in the late eleventh century. Like Brack Mount, it first carried a wooden palisade before receiving a masonry shell keep in the early twelfth century. Towers were added to one of the shell keeps in the thirteenth century. The arrangement of two mottes is unusual among English castles, and Lincoln Castle is identified as the only other English example with this plan.
Bailey defenses and entrance
Curtain wall
The bailey was enclosed by a stone curtain wall, a defensive boundary wall, reinforced with towers. The wall was constructed from local limestone and flint blocks. A section measuring approximately 10 by 10 metres collapsed in 2019 onto an adjacent house and garden, while the surviving castle defenses remain part of the site’s physical fabric.
Barbican gate
A barbican gate was added in the fourteenth century. This outer defensive structure protected an entrance to the castle and formed a later addition to the defenses surrounding the bailey.
