The Domesday Book of 1086 lists the manor as Eitone, one of the numerous holdings throughout England of Odo, Bishop of Bayeux and Earl of Kent, uterine brother of King William the Conqueror.

The outer bailey contained stables for sixty horses, with tiled roofs; a grange, cow houses, pigsties and other thatched buildings; beyond the walls were two gardens, one of three roods the other of one acre.

[7] In its final state the deer park covered about 100 acres (40 hectares), enclosed by a banks and ditches, small sections of which survive.

A deed dated about 1692 mentions "a manor, now known as 'Eaton Park House', surrounded by barns, stables and other outbuildings including a 'stone dovehouse' and a malthouse".

The tithe map of 1849 shows the moated enclosure as pasture called "Park Gardens", and all standing remains on the site had been razed.

[6] In the 19th century Arthur Macnamara (1831-1906) of Billington, known as "the Mad Squire", planned to build a mansion on the site of the castle, but ran out of money after completing the lodge at the entrance to Park Farm.
