Edward III acquired Hadleigh Castle in 1330, when he recovered it from his mother, Isabella of France, who had taken it from Edward when she deposed him in 1326. Edward paid little initial interest to the castle, but in the 1360s decided to make much greater use of the property, ordering large parts of it to be rebuilt at a cost of more than £2200. Between 1361 and 1363 the internal buildings were renovated and new royal lodgings built along the south walls, after which the east side of the castle was rebuilt entirely, with two large circular towers installed in a new stretch of curtain wall, completed by 1365. The north side of the castle was rebuilt to include a main entrance with a portcullis and a drawbridge, protected by a barbican and a large circular tower called the "High Tower", which was complete by 1370. The work was probably overseen by William of Wykeham.
