The Gatehouse website record for Beaumont Castle, Mixbury

In the civil parish of Mixbury. In the historic county of Oxfordshire (Modern Authority of Oxfordshire, 1974 county of Oxfordshire).

Earthworks of a probable defended timber hall with a double court. There is alleged to have been a motte on the site which was supposedly removed during amateur excavations in 1954-5. The field investigator in 1973 was sceptical of this assertion. 2 ditched and ramparted enclosures of C12 castle, fragments of masonry found and small mound may cover base of tower. Probably adandoned before 1216. The manor was granted to Oseney Abbey by Thomas de St Valery in 1213.
Beyond the church, on the north side of Church Lane, the impressive banks and ditches of Beaumont castle can be seen. No masonry remains above the ground and the earthworks alone survive of this important early medieval fortification. This castle was probably built by Roger d'Ivry and nicknamed Beaumont because the ground north of it falls to the stream. Recent excavations (1954–5) revealed a deep well or dungeon at the north-west corner of the earth ramparts with an underground passage leading out of it. (VCH 1959) The account of the underground passage was a personal one given to the VCH and, as far as I aware, the 1950's excavations did not get into print.
