Sutton Valence Castle was probably built in the second half of the 12th century by the Counts of Aumale, most likely by Baldwin of Bethune, but perhaps alternatively by William le Gros, Baldwin's father-in-law. The castle was built on a commanding position overlooking the strategic route between the towns of Maidstone, Rye and Old Winchelsea. and the location was originally known as Town Sutton. The stone keep of the castle was constructed around 1200. In 1203, Baldwin gave the castle to his daughter Alicia on her marriage to William Marshal, the Earl of Pembroke, who later remarried, passing the property to his second wife, Eleanor. After William's death, Eleanor married Simon de Montfort, the Earl of Leicester. Simon led a rebellion against King Henry III during the Second Barons' War, but was killed at the Battle of Evesham in 1265, after which Eleanor was stripped of the castle. The King gave Sutton Valence to William de Valence, his half-brother, who had supported him during the conflict. Under William, the castle acquired its current name of Sutton Valence. Aymer de Valence, his son, inherited the castle in 1307. The Valences travelled around their estates, increasingly focusing their attention on a handful of their various great houses, and stayed at Sutton Valence on at least several occasions. After Aymer's death in 1324, the castle passed by marriage to Lawrence, Lord Hastings, and was held in the Hastings family until 1390, when Reginald Lord Grey de Ruthin acquired it. There are few historical records of the castle beyond this point, but it appears to have been abandoned in the early 14th century and by the 15th century had become ruined.
16th – 21st centuries
By the end of the 18th century, the historian Edward Hasted described Sutton Valence Castle as being "now almost covered with ivy, and the branches of the trees which sprout out from the walls of it." Archaeological excavations were carried out at the site during the mid-1950s with the assistance of Maidstone Museum and the local Sutton Valence School, focusing on the castle keep. The castle was placed into the guardianship of the state in 1976; it is now owned by English Heritage and conservation work was done on the ruins in the 1980s. It is protected under UK law as a Grade II listed building and as a Scheduled Monument.
Architecture
Sutton Valence Castle occupied a spur of the Chart Hills, adjacent to the village of Sutton Valence, and probably comprised an inner and an outer bailey and a protective barbican. Visitors would have entered through an eastern barbican, coming through to an outer bailey; these features only survive as earthworks. A dry ditch protected the inner bailey, which was approximately across, positioned on the southern side of the site. It probably included a hall, chapel and kitchen, but only the castle keep now survives. The keep is square, with walls thick, built from ragstone and flint rubble and surviving up to high. It was originally tall, with at least three storeys, and entered through an external staircase leading to a doorway in the first floor. The building had a corner tower, in which was a spiral staircase linking the floors, and had clasping buttresses at the corners.
