History of Castle AcreCastle (Time Line)

Castle Acre Castle has stood its vigil over River Nar since it rose as a Saxon fortress of earth and timber in 1070. The castle grew extensively in the 12th century, when the great hall became a stone keep. Castle Acre Castle fell into ruin in the mid 1400s.

-1066 (Norman Conquest)

Norfolk was a thriving and densely populated community, and a Saxon landowner named Toki owned the Castle Acre settlement. After the Norman victory at the Battle of Hastings, they deprived Toki of his estates and granted the property to a Flemish warrior named Gerbod. Gerbod then passed the land on to his daughter Gundred.

-1070 (Fortified)

Willam de Warenne married Gerbod's daughter and assumed control of the Castle Acre and estates. A favoured follower of William the Conqueror, Warenne built the first ringwork fortification with no keep or motte and constructed instead of a circular inner bailey with a stone house in the centre.

The fortification offered a base to administer his extensive estates, with easy access to Peddlers Way, a major Roman road. The site also provided easy access to the River Nar, which helped him control the area around the fort.

Warenne also established a small number of Cluniac monks on his estate, which formed the beginnings of the later Cluniac priory. 


William II de Warenne succeeded his father in 1088 and also had an impressive military career. It was under his largesse that the monks began building the Castle Acre Priory. 

-1138 (Improved Defences)

Another William succeeded his father, namely William III de Warenne. William III de Warenne was born to politically sensitive times where Matilda, daughter and rightful heiress of Henry I, fought for control of the Crown against her cousin King Stephen. Due to the political tension, William III de Warenne improved the fort defences and raised the earth ramparts, and strengthened them with stone. 

He then set about converting the once two-story residential house into a defensible military tower. He is also presumed to have fortified the surrounding town with substantial earthworks and ditches. 


William de Warenne III died in the Crusades and left the Castle and lands to his daughter. She married twice, and her second husband was Hamelin Plantagenet, half brother to Henry II. Historians credit Hamelin with the building of the two gatehouses.


Hamelin's heirs also reached political and military prominence in their own right, entertaining royalty at Castle Acre Castle, including King Henry III and Edward I. 


The last of the direct line of de Warenne heirs, John the 8th Earl, dies, and Richard Fitzalan takes control of the castle and lands. His descendants kept ownership of Castle Acre Castle until 1158, although historical records indicate the castle was in a state of decline as early as 1397. 


Thomas Howard, 4th Duke of Norfolk, sold the castle to Thomas Gresham, whose widow sold it to Thomas Cecil, son of Robert Cecil, 1st Earl of Salisbury.

-1615 (Ruins)

Edward Coke, a successful lawyer and political figure, then bought the castle, which was in a state of ruins.


Antiquarian Henry Harrod noted that the townspeople had so recklessly plundered the castle ruins that almost every house had part of the castle's stone. 

-1971 (Listed)

The Fifth Earl of Leicester placed the castle in state guardianship, and the castle Grade I listed buildings in Norfolk.


Johnathon Coad and Anthony Streeten conduct extensive excavations of the castle site.


Today, the Castle is a Grade I listed monument, and English Heritage UK is the custodian of the castle ruins.

Castle Acre Castle Facts

Castle Acre Castle is one of the finest examples of a well-preserved motte and bailey castle and an excellent example of Norman earthworks. The first stone building constructed in the centre of an inner bailey was a two-story residential building. It stood in a courtyard, protected by a ditch and bank which survives buried beneath later earthworks.

Around 1140, William III de Warenne began converting the house into a keep. He also set about to strengthen the surrounding defences, enlarged the ditch, raised the bank, and began constructing the curtain wall. 

Later, the second fortification period raised the perimeter bank and built a second curtain of flint on the existing curtain wall. Builders added the east and western gatehouses to provide entry to the outer bailey.

Archaeologists believe that the foundations that remain in the outer bailey are evidence of a great hall, separate kitchen, and a chapel. Experts also believe that the hall replaced the original house in the inner bailey after converting it into a keep.

Castle Acre Castle Q&A

What Kind of Castle Is Castle Acre?

Originally a Saxon fortress made of timber and earthworks, the medieval fortress was made of a high motte at the north end and an extensive outer bailey to the south, and a smaller bailey to the east. 

Builders covered earthwork ramparts with stone walls and transformed the original stone domestic building into a keep in the 12th century. The occupants surrounded the castle in earthwork defences and added stone gatehouses of which the Bailey Gate still stands. 

How Big Was Castle Acre?

The settlement of Castle Acre was 225 by 188 meters (738 by 617ft) and covered an area of some 10.5 acres (4.25 hectares) the surviving ditch is around 17 metres wide (56ft) and 3 metres deep (9.8ft) later Builders also raised the banks to a height of 3 metres (9.8ft)
