Knapwell Overhall Grove has been described as a probable Timber Castle.

There are earthwork remains.

This site is a scheduled monument protected by law.


Mound, perhaps a small Norman motte, on the flat Kimmeridge clay floor of the valley, 50 yards W of the stream. Finds made during an unpublished excavation in 1929 include St Neots ware from 2ft to 3ft below the surface of the mound. The mound is circular, 6ft high and 80ft in diameter with a flat top 30ft to 40ft across. The wet ditch is 30ft wide on the NE and 20ft wide on the SW and holds about two and a half feet of water. On the SW the ditch is crossed by a flat causeway 10ft wide which, in view of the cupped ends of the ditch on either side, is probably original. On the N and W a bank 15ft wide and 1ft to two and a half feet high may be the remains of an outer enclosure or merely a hedge bank separating the mound and ditch from an area of ridge and furrow to the N. (RCHME 1969)

The medieval Overhall manor house presumably stood amid the ancient enclosures in the north part of Overhall grove, inside the rectangular moated site, c. 35 m. by 40 m., whose southern ditch is still wet. Pottery fragments indicate habitation there from the 11th century to the 14th. That moat is surrounded by an irregularly embanked enclosure, c. 165 m. by 210 m., possibly intended for keeping cattle. Perhaps no longer occupied after the Lovetts inherited the manor, the house had disappeared well before 1600. The earthworks, entirely concealed by trees by 1650, were rediscovered only c. 1900.

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
