Donnington Castle lies to the north of Newbury in Berkshire and is in the care of English Heritage. The monumental gateway forms part of the 14th century development. During the Civil War the castle was seized by the Royalists, and finally surrendered to the Parliamentarian forces in 1646 when all but the gatehouse was demolished.
The castle was placed in State Guardianship in 1946. Margaret Wood wrote the MPBW guide in 1964 [WorldCat]. Wood also wrote the Ministry guides to Old Soar Manor (1950), Burton Agnes Old Manor House (1956), and Christchurch Castle (1956).
