Thetford Castle is a medieval motte and bailey castle in the market town of Thetford in the Breckland area of Norfolk, England. The first castle in Thetford, a probable 11th century Norman ringwork called Red Castle, was replaced in the 12th century by a much larger motte and bailey castle on the other side of the town. This new castle was largely destroyed in 1173 by Henry II, although the huge motte, the second largest man-made mound in England, remained intact. The motte, recognised as a scheduled monument, now forms part of a local park, and the remains are known variously as Castle Hill, Castle Mound and Military Parade.

History[edit]

11th century[edit]

In the 11th century the largest towns in England were concentrated in the east and south-east of the country, especially in East Anglia.[1] Thetford was an important settlement during the period and the second largest town in East Anglia.[2] Thetford comes from "Thaetford", or "the ford", and was a key point on the ancient Icknield Way.[3] Thetford was also an important international trading hub and a centre of pottery production. An earth and timber fort had been built on this site during the Iron Age period but had been left to decay and by the late Saxon era the town had been protected by a burgh, or ditched enclosure, that surrounded the town.[4]

The first castle on the Thetford site was Red Castle and was probably built shortly after the Norman conquest of England by William de Warenne, the Earl of Surrey.[5][nb 1] The castle was a ringwork design and was positioned across the line of the defensive Saxon ditch, in the process enclosing and cutting off the local church from the inside of the town, and building over part of the local cemetery.[7][nb 2]

12th century[edit]

By 1100, the town of Thetford was controlled by Roger Bigod, the Earl of Norfolk.[10] Roger Bigod decided to build a new motte and bailey castle, positioning it so as to guard both the town and the local crossing of the Icknield Way over the River Thet and the Little Ouse.[11][nb 3]

At the heart of the castle was a huge motte, or artificial mound, sunk into a deep surrounding ditch, and protected on the north site by two sets of complex ramparts, which were probably part of the original Iron Age fortifications of the site.[13] At 19.6 m (64 feet) high - 22 m (72 feet) from the base of the ditch - and 100 m (328 feet) wide across the base, this is the second largest man-made mound in England.[14][nb 4] The castle would have probably included a large timber keep on top of the motte, and a rectangular bailey fortification, approximately 105 m by 95 m (344 feet by 312 feet), stretched away from the motte, exploiting the former Iron Age fortifications on one side.[15][nb 5] The new castle would have loomed over, and dominated, the former Saxon town.[17]

The castle earthworks were built up from local chalk; the ditches dug around the fortification would not have provided enough for the mound itself, and local tradition suggests that much of the earth was quarried instead from the nearby Gallows Pits in the town.[18] The castle was constructed by hand, using workers digging with wooden shovels, and probably without pickaxes.[19] It is estimated that the motte would have taken around 24,000 man days of effort to build.[20]

The Bigod family continued to build their grip on the region, taking advantage of their powerful castles at Thetford, Framlingham, Bungay, and Walton.[21] Roger's son, Hugh Bigod, played a prominent role during the civil war years of the Anarchy, rebelling against King Stephen from his strongholds in East Anglia. It appears likely that a stone wall had been built around the bailey around this time, and recent work has speculated that a stone keep was also erected on the site.[22] At the end of the war, however, Henry II took the throne and attempted to restore royal power across the region.[23] In 1157, Henry seized Bigod's castles; he ultimately returned Framlingham and Bungay, but retained Thetford Castle for his own use.[23] Hugh Bigod then joined the revolt by Henry's sons, seizing the castle, but in 1173 Henry's forces captured the castle and destroyed the fortifications.[24] The mound, however, proved effectively indestructable.[25]

13th–20th centuries[edit]

Thetford declined after the 12th century, and the castle rapidly became disused, although as late as 1558, the Castle Yard was in use and still said to have been surrounded with a stone wall.[26] In 1772 the east bank of the outer bailey was destroyed.[27] In 1823 a group of elm trees were planted near the top of the mound.[28]

Interest continued in the origins of the castle, which for a period were forgotten. Local medieval tradition suggested that the mound had been made by the devil, after he completed the dykes at Narborough and Newmarket, but by the Victorian period academics had concluded that the mound was either of Celtic or Norman origin, with late Victorian scholars correctly concluding that the Norman period was the most likely.[29] Other traditions claimed that the mound covered a palace filled with treasure, or six silver bells from Thetford Priory.[30] Archaeological investigations into Red Castle by G. Knocker between 1957–58, and during the early 1960s by R. R. Clarke and Barbara Green revealed the design and date of this castle site.[31]

21st century[edit]

Today the motte is owned by the local authority and forms part of the Castle Park; the castle bailey is now known as Military Parade.[32] The site is a scheduled monument.[27]

Notes[edit]

  1. ^ An alternative argument, supported by archaeologists Paul Everson and Marcus Jecock, is that the castle was a mid-12th century product of the Anarchy.[6]
  2. ^ Earlier work had suggested that Red Castle was a motte and bailey design, with a heavily sunken centre.[8]
  3. ^ Archaeologists Paul Everson and Marcus Jecock argue that the castle may have been built by William de Warenne or William the Conqueror.[12]
  4. ^ The largest man-made mound in England is Silbury Hill.
  5. ^ Earlier archaeological studies had suggested that the bailey itself was largely an Iron Age fortification, but recent studies have discounted this, arguing that only part of the bailey enclosure was of Iron Age origins, with the majority of medieval origins.[16]
