Thetford Castle

Details

Thetford Castle's most striking feature is its colossal man-made mound, the second largest in England, offering panoramic views across Norfolk to those who climb its 40-foot height. This impressive earthwork was originally part of an Iron Age hillfort, strategically positioned to control the ancient Icknield Way and the river crossings of the Thet and Little Ouse. Around 1067, shortly after the Norman Conquest, a timber fortification was erected within these existing defences. Later, in the 12th century, a more substantial motte and bailey castle was constructed by Roger Bigod, Earl of Norfolk. This formidable structure dominated Thetford, then one of England's largest towns, serving as a powerful symbol of Norman authority and a key defensive site.

Though the original castle buildings were largely destroyed in 1173 by Henry II following a revolt, the immense earthen motte proved virtually indestructible and remains today as the heart of Castle Park. Visitors can explore these ancient earthworks, now a scheduled monument, and imagine the bustling medieval fortress that once stood here. The site also has intriguing local legends, including one that claims the Devil himself formed the mound. Easily accessible in the centre of Thetford, the park provides a tranquil space for a walk or picnic amidst layers of history, with informative plaques often available to enrich your understanding of this significant landmark.
