Lewes Castle

Lewes Castle is a Norman-era motte-and-bailey fortress in the town of Lewes, East Sussex, England, notable for its unusual pair of mottes created soon after the Norman Conquest. The ruins include earthworks, remnant masonry and interpretation displays for visitors.

The twin mottes and surviving sections of curtain wall and gate structures which together illustrate medieval defensive planning in a small town context. The site has a visitor route and museum displays that explain the castle’s construction and local role in medieval Sussex.

The castle was built in the late 11th century by the first Norman lords of the area and remained a focal point of regional power through the Middle Ages, later falling into ruin and partial preservation as a historic monument. Conservation and interpretation work have been undertaken to stabilise visible masonry and explain the site to the public.

The castle sits on a hill above the centre of Lewes town, overlooking the River Ouse and the surrounding South Downs landscape in East Sussex.

• Architectural rarity: Constructed soon after the Norman Conquest, the castle retains an uncommon double-motte layout visible from the town and South Downs ridge.
• Viewing points: Perched above the town of Lewes, the site provides clear views over the Ouse valley and the South Downs, making the mottes effective medieval observation points.
