Visit Burgh Castle Roman Fort in Norfolk. Explore one of the best-preserved Roman forts in Britain with massive stone walls overlooking the Broads.

A Fort on the Saxon Shore

Burgh Castle Roman Fort, near Great Yarmouth in Norfolk, was built in the late 3rd century AD as part of the Saxon Shore forts—a chain of coastal defences guarding Roman Britain against seaborne raiders. Known to the Romans as Gariannonum, it once housed a garrison of cavalry who patrolled both land and sea routes.

Its huge flint and stone walls still stand today, making it one of the most impressive Roman remains in East Anglia.

The Roman Walls

Three sides of the fort’s stone walls survive almost to their original height, standing over 4 metres tall in places. The fourth side, which faced the river, has disappeared—once open to the water for easy supply by boat.

The walls include massive bastions where towers projected outward, allowing soldiers to defend against attackers with arrows and catapults.

From Romans to Monks

After the Roman army left Britain in the early 5th century, the fort may have been reused by early Saxons. In later centuries, it became the site of an early Christian monastery founded by St Fursey in the 7th century, linking it to the spread of Christianity in East Anglia.
