Aldermaston /ˈɔːldərmɑːstən/ is a mostly rural, dispersed settlement, civil parish and electoral ward in Berkshire, South-East England. In the United Kingdom Census 2011, the parish had a population of 1015. The village is in the south the mid-Kennet alluvial plain and bounds to the south Hampshire. It is roughly equidistant from Newbury, Basingstoke and Reading, centred 46 miles (74 km) west-by-south-west of London.
Aldermaston may have been inhabited as early as 1690 CE; a number of postholes and remains of cereal grains have been found in the area. Written history of the village is traced back at least as far as the 9th century AD. The Anglo-Saxon Chronicles show that the Ealdorman of Berkshire had his country estate in the village. The manor of Aldermaston was established by the early 11th century, when the village was given to the Achard family by Henry I; the manor is documented in the Domesday survey. The village church was established in the 13th century, and some of the original Norman architecture remains in the building's structure. The last resident Lord of the Manor, Charles Keyser, died in 1929. The manor estate has been subsequently occupied by Associated Electrical Industries, the XIX Tactical Air Command, the Women's Land Army, Collier Macmillan Schools, and Blue Circle Industries. The manor house is now run as a private corporate venue by the Compass Group.
