Castle at Alrehede/Aldreth was constructed in 1071 and held against King Stephen between 1140-1143, in which year it was captured. Built by William I in campaign against Hereward. Renn suggests either Belsar's Hill or Braham as possibilities. PastScape gives general location of Aldreth village.
A wooden fortress is said to have existed at Aldreth according to C13 historian, Matthew Paris. It was known as "Hereward's Castle". It also recorded that a castle was built at Aldreth by Nigellus, Bishop of Ely, as a defence against King Stephen (1135-54) (Evelyn-White). The castle of Alrehede is mentioned by the 'Liber Eliensis' in connection with the defence of the Isle of Ely in 1069-71. It was refortified in 1139. "Identification is doubtful but a suggested site is Belsar's Hill, Willingham" (TL 47 SW 24)" (Renn). (PastScape)
