The Manor of East Barming is mentioned in Domesday and was owned by the Clare family. The Barming moiety of the manor was given to the Benedictine nunnery of St. Helen's in London. A Norman Manor house was built west of the Church in Barming and the bridge across the River Medway, 450m to the south east, is also known as St. Helen's Bridge. All buildings were cleared away by 1844, the eel house being the last to survive. The manor site today is marked by a hollow where the cellars appear to have been, 18 yards or 16.46m from the churchyard wall. It has been incorporated into an extension of the graveyard. No evidence of building materials has been found in archaeological excavations or in grave cutting, although broken tile fragments are scattered on the surface. Coins found at the Roman Villa site (TQ 75 SW 22) include a silver penny of Edward I.
