Thetford Castle

Thetford Castle stands on a large man-made mound in the market town of Thetford, Norfolk. The mound is the second-largest of its kind in England and forms part of Castle Park. The castle began as a Norman ringwork in the 11th century, built by William de Warenne, Earl of Surrey. In the 12th century, Roger Bigod, Earl of Norfolk, replaced it with a motte-and-bailey design. The motte was constructed by hand using local chalk and took about 24,000 man-days to complete. The site was once a powerful stronghold for the Bigod family, who controlled much of East Anglia. During the Anarchy, Hugh Bigod rebelled against King Stephen from Thetford Castle. Henry II later captured and slighted the castle in 1173, though the motte survived intact. The castle’s remains are now a scheduled monument, recognised for their historical significance. Visitors to the site find a grassy mound with wide views over Thetford. The bailey area, now called Military Parade, lies below the motte. The park includes elm trees planted in 1823 near the mound’s summit. The castle’s history is marked by legends, including tales of a buried palace or treasure. Archaeological work in the 20th century uncovered details of the earlier ringwork castle. Today, the site offers a quiet place to explore the remains of a once-dominant fortress.
