[4] William Malet's son, Robert, was exiled and after his death at the Battle of Tinchebray in Normandy in 1106, Eye was confiscated by Henry I and became a royal castle for a period.

[6] Stephen succeeded to the English throne in 1135 and he gave the honour of Eye first to one of his lieutenants, William of Ypres and then later to Hervey Brito, his son-in-law.

Eye Castle did not play a major role in the war as, despite some skirmishing occurring in the region, most of the campaigning was conducted to the west.

[10] Partially as a result of the civil war, Hugh Bigod had come to dominate East Anglia by the late 12th century, holding the title of the Earl of Norfolk and owning the four major castles in the region, Framlingham, Bungay, Walton and Thetford.

[12] Despite having made earlier promises to protect him, Henry still saw Stephen's son, William, as a potential claimant to the throne, and the king confiscated the castle of Eye as well at the same time.

Two square towers were built on the north side of the inner bailey in the late 12th century, possibly contemporaneously with Framlingham Castle.

[21] The mound and some stone fragments of the original castle still remain intact, and the site is a scheduled monument and a Grade I listed building.
