Castle Acre Castle and Town Walls

Norman Origins and Construction

Castle Acre Castle was constructed in the 1070s by William de Warenne, a key ally of William the Conqueror who fought at the Battle of Hastings. Located at the strategic junction of the River Nar and the ancient Peddars Way Roman road, the site was originally an Anglo-Saxon manor owned by Toki, seized post-Conquest and granted to de Warenne through marriage. The initial motte-and-bailey design featured large earthwork ramparts protecting outer and inner baileys, with a stone-built double-hall in the motte's center serving as a grand residence rather than a fortified keep.

Fortifications During the Anarchy

During the civil war of the 1130s-1150s known as the Anarchy, William de Warenne III significantly strengthened the castle. He raised earthworks, crowned them with stone walls, and began converting the hall into a tall square keep. The outer bailey gained stone-faced ramparts and gatehouses, while the adjacent town was enclosed by massive banks and ditches, redirecting the Peddars Way past the castle, town, and nearby priory to symbolize de Warenne dominance.

Decline and Later Ownership

The de Warenne family held the castle until 1347, after which it passed to the Fitzalans and others, falling into neglect by the 15th century. Post-Dissolution of the Monasteries, Thomas Howard, Duke of Norfolk, leased the ruins in 1537. Sold in 1558 to Thomas Gresham and later to Sir Edward Coke in 1615, it remained in private hands. By the 18th century, it attracted antiquarians; English Heritage has managed preservation since 1984.

Visiting the Ruins Today

The free-to-enter site reveals well-preserved earthworks, the inner bailey's stone wall fragments, and imposing gatehouses. Climb the motte for views over the village and priory. The vast outer bailey hints at its former scale, with traces of a chapel and great hall. Surrounded by lush Norfolk countryside, it's a peaceful spot for exploration, best in daylight to appreciate the defensive genius.

Historical Significance

As one of England's finest motte-and-bailey examples, Castle Acre exemplifies early Norman castle-building and adaptation. Its town walls and priory connection highlight medieval planning. Free access preserves its role as a public heritage gem, drawing walkers on the Peddars Way trail.
