Christchurch Castle is located in Christchurch, Dorset, England. The earliest stonework has been dated to 1160. It is a Norman motte and bailey castle. The castle’s site is inside the old Saxon burh dominating the River Avon’s lowest crossing.
The Constable’s House standing adjacent to the castle was added at around 1160 and is a rare and notable example of a Norman domestic dwelling. Today the bailey is home to a bowling green and gardens, and the ditch has been filled but parts of the keep and much of the constable’s house still stand.
The castle is believed to stand on the site of an earlier wooden fort built in 924 following the capture of the town ramparts in 901 by King Aethelwold of Wessex and subsequently fortified with a motte by King Edward the Elder. After the Norman conquest of 1066, the castle’s defenses were strengthened by the addition of a ditch and bailey surrounded by a wooden palisade. The wooden fort was eventually replaced with a stone keep. The Norman castle was a strategic defensive structure controlled by the King’s constable until King Henry I (r. 1100–1135) granted it as the caput of a feudal barony to his cousin Richard de Redvers (died 1107), feudal baron of Plympton, Devon.[3] While the Saxon defenses had been against outside threats such as Viking raiders, the Norman fortress was more concerned with subduing the local populace. It was also a useful base for enforcing the New Forest Laws. The castle controlled the harbor and inland access via the Rivers Avon and Stour. The earliest masonry has been dated to c. 1160, and there is documentary evidence of the castle existing in c. 1130. Richard de Redvers has often named as the castle’s first builder, although there is little documentary evidence of this and this castle may well have been on the site of the earlier Saxon castle. The castle was rebuilt by Baldwin de Redvers to resist King Stephen during the civil war with Empress Matilda in 1147. A great tower was built probably around 1300. The castle again saw action during the Civil War of 1642–1651. The Parliamentarians were allowed to take control of the castle in 1644. The Royalists laid siege to it for 3 days, demolishing houses on the corner of Church Street and Castle Street in order to site their cannons. The Royalists were unable to take the castle and Oliver Cromwell, fearing such a powerful stronghold, ordered it to be slighted in 1652. The castle is now in ruins; a couple of the keep walls remain and the remains of a rectangular moat.
