About
Pevensey Castle in East Sussex occupies one of the most historically charged sites in Britain — a Roman fort of the 4th century AD, within whose massive walls William the Conqueror landed in 1066, establishing his first foothold in England before marching to the Battle of Hastings. The conjunction of Roman, Norman, and later medieval layers at a single site makes Pevensey extraordinary: it is not one castle but a palimpsest of defensive history stretching across fifteen centuries, from the last days of Roman Britain to the Second World War.
The Romans built Anderida as one of the Saxon Shore forts around 290 AD, a chain of coastal fortifications designed to defend Britain against raids from across the North Sea. The oval circuit of walls — still standing to considerable height in places — enclosed an area of nearly ten acres and was defended by projecting bastions of characteristic Roman form. These walls, built of coursed ragstone with bonding courses of tile, survive as some of the most impressive Roman military remains in Britain, giving Pevensey its unique visual character even before the Norman inner castle is considered.
William the Conqueror landed at Pevensey on 28 September 1066 — the first action of the Norman conquest of England. He used the existing Roman walls as the outer boundary of an instantly improvised fortification, and within days had erected a wooden castle within the Roman enclosure. This was subsequently replaced in stone, and the inner bailey wall, keep, and gatehouse that visitors see today are largely the work of the late 11th and 12th centuries under successive Norman lords. The castle was besieged several times in the Middle Ages and changed hands repeatedly in the baronial conflicts of the period.
Pevensey has one of the most remarkable afterlives of any English castle. During the Second World War, as German invasion threatened in 1940, Pevensey was fortified again — gun emplacements, observation posts, and pillboxes were built using the Roman and Norman walls as part of a contemporary defensive system. The wartime additions are still visible today, including a machine gun post concealed in the Roman masonry, making Pevensey a site where Roman, Norman, medieval, and 20th-century defences can all be read simultaneously in the same fabric.

💡 Visitor Tips
- Allow 90 minutes to walk the full circuit of the Roman walls, explore the inner castle, and find all the wartime gun emplacements hidden in the ancient masonry.
- Look carefully at the Roman masonry near the north-west corner — the wartime machine gun position is concealed within the original Roman wall, camouflaged with remarkable skill.
- Pevensey village itself is charming — the Court House Museum (small, free, in the medieval courthouse) is worth 20 minutes alongside the castle.
- The castle is a natural stop on the '1066 Country Walk' — a long-distance trail linking the key 1066 sites from Pevensey to Battle Abbey and Hastings.
- Trains from Eastbourne reach Pevensey & Westham station in 10 minutes, making this an easy addition to a day in Eastbourne.
- English Heritage members enter free — Pevensey pairs well with Battle Abbey (EH, 20 minutes by car) for a full 1066 day.
Highlights
The Roman Saxon Shore Fort — Anderida
The Roman walls at Pevensey are among the most impressive Roman military remains in Britain. Built around 290 AD as one of the Saxon Shore forts defending late Roman Britain, the oval circuit encloses nearly ten acres and survives in places to over 7 metres. Built of coursed ragstone with bonding courses of red tile — characteristic late Roman technique — the walls are punctuated by projecting D-shaped bastions allowing flanking fire.
Walking the circuit of these walls, some standing for nearly 1,800 years, is one of the most powerful experiences of Roman Britain in the south of England. The sheer scale of the original fort, still legible in the landscape, gives a visceral sense of late imperial military ambition.
William the Conqueror Landed Here — 1066
Pevensey's place in English history is indisputable: it was here, on 28 September 1066, that William landed with his invasion fleet, making his first foothold on English soil before the Battle of Hastings fourteen days later. William chose Pevensey because the Roman walls provided immediate defensible enclosure — he erected a wooden castle within them almost immediately.
This moment — the Norman army arriving through the gap in walls that had stood vacant for perhaps two centuries — is one of the decisive scenes of British history.
Pevensey provides an extraordinarily evocative setting in which to imagine it, and the overwhelming presence of the Roman walls makes the Norman reuse of them viscerally understandable.
The Norman Inner Castle
Within the Roman enclosure, the Norman lords built a stone inner castle whose walls, twin-towered east gatehouse, and keep survive in atmospheric ruin. The inner bailey dates largely from the late 11th and 12th centuries; the gatehouse, with its unusual projecting towers flanking the gate passage, is one of the more interesting examples of late Norman military architecture in England.
The spatial relationship between the massive Roman outer walls and the more intimate Norman inner castle creates a sense of layered time unique to Pevensey — two systems of military engineering, separated by eight centuries, occupying the same ground and reinforcing each other in ways neither of their builders could have anticipated.
The Medieval History of Sieges
Pevensey Castle was repeatedly contested in the baronial conflicts of the Middle Ages. Besieged by William Rufus in 1088 after rebellion; besieged again in 1147; contested during the Stephen-Matilda civil war. The castle's strategic importance controlling the coastal lowland of the Pevensey Levels made it a consistent prize in every conflict affecting the region.
Its eventual decline was gradual — the levels were drained, coastal geography changed, and the natural water defences that had made the Roman site formidable gradually disappeared. By the 15th century the castle was largely abandoned, its three distinct systems of defence rendered obsolete by changing technology and landscape.
