Baconsthorpe Castle, historically known as Baconsthorpe Hall, is a ruined, fortified manor house near the village of Baconsthorpe, Norfolk, England. It was established in the 15th century on the site of a former manor hall, probably by John Heydon I and his father, William. John was an ambitious lawyer with many enemies and built a tall, fortified house, but his descendants became wealthy sheep farmers, and being less worried about attack, developed the property into a more elegant, courtyard house, complete with a nearby deer park.

The castle was built soon after the Norman Conquest by William de Warenne, the Earl of Surrey, at the intersection of the River Nar and the Peddars Way. William constructed a motte-and-bailey castle during the 1070s, protected by large earthwork ramparts, with a large country house in the centre of the motte. Soon after, a small community of Cluniac monks were given the castle's chapel in the outer bailey; under William, the second earl, the order was given land and estates to establish Castle Acre Priory alongside the castle. A deer park was created nearby for hunting.

Castle Rising is a ruined medieval fortification in the village of Castle Rising, Norfolk, England. It was built soon after 1138 by William d'Aubigny II, who had risen through the ranks of the Anglo-Norman nobility to become the Earl of Arundel. With his new wealth, he constructed Castle Rising and its surrounding deer park, a combination of fortress and palatial hunting lodge. It was inherited by William's descendants before passing into the hands of the de Montalt family in 1243. The Montalts later sold the castle to Queen Isabella, who lived there after her fall from power in 1330. Isabella extended the castle buildings and enjoyed a regal lifestyle, entertaining her son, Edward III, on several occasions. After her death, it was granted to Edward, the Black Prince, to form part of the Duchy of Cornwall.

It was founded in the aftermath of the Norman conquest of England when William the Conqueror (1066–1087) ordered its construction because he wished to have a fortified place in the town of Norwich. It proved to be one of his two castles in East Anglia, the other being Wisbech. In 1894 the Norwich Museum moved to Norwich Castle and it has been a museum ever since. The museum & art gallery holds significant objects from the region, especially works of art, archaeological finds and natural history specimens.

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.

Weeting Castle is a ruined, medieval manor house near the village of Weeting in Norfolk, England.

A moat was later dug around the site in the 13th century. The house was not fortified, although it drew on architectural features typically found in castles of the period, and instead formed a very large, high-status domestic dwelling. It was probably intended to resemble the hall at Castle Acre Castle, owned by Hugh's feudal lord, Hamelin de Warenne.
