Aldermaston ( ) is a village and civil parish in Berkshire, England. In the 2011 census, the parish had a population of 1,015. The village is in the Kennet Valley and bounds Hampshire to the south. It is approximately from Newbury, Basingstoke, and Reading and is from London.

Aldermaston may have been inhabited as early as 1690 BCE; 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 CE, when the Anglo-Saxon Chronicles showed 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 Book of 1086. St Mary the Virgin 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. Aldermaston Court, the manor estate and house, was requisitioned for armed forces use during the Second World War.

The name "Aldermaston" is well known in connection with the UK's nuclear weapons programme, as well as the Campaign for Nuclear Disarmament. The Atomic Weapons Establishment (AWE), which develops, maintains, and disposes of the UK's nuclear weaponry is in the parish. Built on the site of the former RAF Aldermaston, the plant has been the destination of numerous Aldermaston Marches.

Toponymy The village of Aldermaston derives its name from Ældremanestone, Eldremanestune or Hedlremanestone, the Old English for "Ealdorman's Homestead". The Ealdorman—or Alderman—was a person of extreme importance, equating to the modern-day Lord-Lieutenant of the county. Although his country estate was in Aldermaston, he would have spent most of the time in the original county town of Wallingford. The Anglo-Saxon Chronicle states that the first known Ealdorman of Berkshire, Aethelwulf, fought the Danes with Ethelred of Wessex at the nearby Battle of Englefield in 871. Other documented names include Aldermaston ad Pontem (11th century), Aldremanneston (12th century), Aldremaneston (13th century), Aldermanston and Aldermanneston Achard (14th century), and Aldmerston (19th century).

History

Evidence suggests that Aldermaston was inhabited in the 12th century CE, possibly extending back to 1690 BCE. Radiocarbon dating on postholes and pits in the area show activity from 1690 to 1390, 1319 to 1214, and 977 to 899 BCE. Wheat and barley grains have been found in these excavations. Tests show that most of the barley was dehulled, but that absence of such debris may mean that the cereal was brought in from other areas.

Middle Ages Before the 1066 Norman Conquest, the land and properties of Aldermaston formed part of the estates of Harold Godwinson, the Earl of Wessex, who later became King Harold II of England. Harold's assessment of Aldermaston valued the village's 15 hides at £20 a year. As with much of the land seized by William the Conqueror after his arrival in England in 1066, Aldermaston was held in demesne. His Domesday Book of 1086 identified the existence of a mill, worth twenty shillings, and two fisheries, worth five shillings. During the rest of William's reign, and that of his son William Rufus, Aldermaston was owned by the Crown.

The history of the Lords of the Manor of Aldermaston Court can be traced to Achard D'Aldermaston, who was born in 1036. Six families have had lordship of the Aldermaston estate. In the 11th century, Henry I gave Aldermaston to Robert Achard (or Hachard) of Sparsholt. In the mid-12th century, the Achard family founded the church of St Mary the Virgin. In 1292, Edward I granted the right for the lord of the manor to hold a market in the village. Another charter was granted by Henry IV, with evidence that the market existed until approximately 1900. The Achards also established an annual fair to observe the feast of St. Thomas the Martyr on 7 July.

Aldermaston was held by the Achard family until the 14th century, when it passed through marriage to Thomas of Nunney Castle, Somerset. The family governed Aldermaston for approximately 120 years, until Elizabeth whose male relatives predeceased her—married into the Forster family. In about 1636, the Forsters built a large manor house to the east of the church. The house incorporated parts of an earlier (15th century) house, including the chimney stacks. The Forsters' house was fronted by two porches, separated by a central section with seven bays. The porches had ornate Solomonic columns, similar to those at the University Church of St Mary the Virgin in Oxford.

The interior of the house featured a number of mythical statues, as well as artwork by Gaspard Dughet, portraits of William Congreve and Godfrey Kneller, and Tintoretto's Esther Before Ahasuerus. The house's Jacobean garden featured patterns of groves and avenues of oak, yew, Spanish chestnut and lime trees. In the early 18th century the Forsters oversaw the building of almshouses in Church Road. Built by R Dixon in 1706, the houses became known as "Dixon's Cottages". The manor passed through the Forster family until 1752, when the Forster lineage ended and the estate was inherited by Ralph Congreve, the husband of the last Forster's grand-niece. On Ralph's death a second-cousin of dramatist William Congreve inherited the manor. The Congreve Family owned the estate at the time of the 1830 Swing Riots. The rioters marched across Aldermaston, wrecking twenty-three agricultural machines. Workers were so frightened by the riots that they left their machinery in the open in an attempt to limit additional damage.

Victorian era

In 1843, the manor house was destroyed by fire, news of which was carried in The Illustrated London News. The estate passed into the Court of Chancery and was purchased by Daniel Higford Davall Burr. In 1848, Burr commissioned the building of a neoclassical mansion to the south west of the original building. Burr saved the 17th-century manor's wooden staircase, though all that remains of the building is a staircase to the cellar (which is now home to a colony of bats). By 1851 the new building was complete, costing £20,000 and having a Tudor-like appearance. Burr held the estate until his death 50 years later, when this was inherited by his son, who sold it in 1893.

The buyer was the wealthy stockbroker Charles Edward Keyser, who was preoccupied with the idea of keeping the village unchanged—or, as he described it, "unspoilt". He forbade advertisements, opposed all modernisation and refused to allow any expansion by the building of houses. He did, however, commission the building of a parish hall in 1897 and provided the village with a water supply, and the water fountain on the small village green was installed to commemorate Queen Victoria's Diamond Jubilee. Keyser oversaw the restoration of the village almshouses in 1906 and 1924, and defrayed the cost of a memorial oak tablet in memory of those killed in World War I. Of the 100 men from the village who served in the war, 22 were killed (the highest percentage of town population in the country). The tablet bears the name of each man lost in action.

During Keyser's lordship, John Marius Wilson's Imperial Gazetteer of England and Wales listed Adminston as a possible name for the village. On his death in 1929, his wife, Mary, continued to occupy the house until she died in 1938. The estate was auctioned off in September 1938, and many lots were purchased by their occupiers. The manor house was bought by Associated Electrical Industries (AEI) for £16,000. One of the houses in the village is recorded as having fetched £1,375. As AEI's chairman, Felix Pole became the de jure Lord of the manor upon their purchase of Aldermaston Court.

Post-World War II During the 1940s RAF Aldermaston was created on the parkland at the southern end of the parish, with the Women's Land Army and the XIX Tactical Air Command stationed on the estate. After World War II, the manor was returned to AEI who built the MERLIN reactor on part of the land. The reactor was opened on 6 November 1959 by The Duke of Edinburgh. With the opening of the Atomic Weapons Research Establishment (AWRE) in 1950, Aldermaston became synonymous with a number of Campaign for Nuclear Disarmament (CND) marches.

In 1953, Pole stepped down as Lord of the manor and was succeeded by AEI's senior representative, Thomas Allibone. Allibone held the position for 32 years, until Blue Circle Industries acquired the estate in 1985. Allibone was succeeded by Tony Jackson, and the current Lord of the manor is Andy Hall. Blue Circle could not gain planning permission in the grounds of the court, so the MERLIN reactor was demolished to make way for Portland House. With a full redevelopment of Aldermaston Manor, the £14 million office development became Blue Circle's international headquarters and the complex was opened by Prince Richard, Duke of Gloucester.

Governance Historically, Aldermaston was a hundred, though for a period it was within the Theale hundred. By the 19th century, the hundreds had been superseded by other sub-divisions. From then on, Aldermaston was, at times, part of the Bradfield Poor Law Union and Sanitary District, and the registration sub-districts of Mortimer (late 19th century) and Bucklebury (early 20th century). It was at all times an ecclesiastical parish and acquired civil parish status in the 1890s.

The civil parish council, elected by local residents, is in the area of West Berkshire unitary authority. The electoral ward of Aldermaston includes the neighbouring parishes of Wasing, Brimpton, Midgham, and Woolhampton and is the smallest ward in West Berkshire by population. The ward's councillor is Dominic Boeck, who represents the Conservative Party. Aldermaston is under the catchment of Thames Valley Police and is covered by the Brimpton Neighbourhood Policing Team.

Geography

Aldermaston is in West Berkshire, about from the Hampshire boundary. The village is south of the A4 road that links the parish with Newbury and Reading. The main road in Aldermaston, The Street, is part of the A340 road and links the village with Pangbourne and Basingstoke. The course of Ermin Way, the Roman road that linked Calleva Atrebatum (Silchester) with Glevum (Gloucester) via Corinium Dobunnorum (Cirencester) runs south of the village, but none of the road survives in the area.

At the southern end of The Street is a small triangular village green called The Loosey—possibly named after a "Lucy" who planted the oak tree which stands on the green. The Loosey is the site of a Roman well, discovered in 1940 by a cow that almost fell down it. The Loosey was previously home to the village maypole (which was often climbed by Daniel Burr's monkey) and a drinking fountain erected by Charles Keyser to celebrate the Diamond Jubilee of Queen Victoria.

The River Kennet and River Enborne flow through the parish, and their confluence is approximately north of the village. The Kennet and Avon Canal forms part of the parish's boundaries with Woolhampton and Padworth. Sections of Grim's Bank are in the parish. Part of the earthwork in the AWE complex survives at a height of and with a ditch deep. The village has a couple of Sites of Special Scientific Interest called West's Meadow and Aldermaston Gravel Pits.

Geology The landscape of Aldermaston is influenced by Paices Hill and Rag Hill, which are extremities of the chalk formation the North Wessex Downs as part of the Thames Basin Heaths. The topography of the land in the parish generally slopes northward to the River Kennet. The soil in the parish is high in clay. Due to the parish's location within the Kennet Valley there is a high concentration of alluvium, with the content largely determined by the London Clay Formation, the Bagshot Formation, and the Bracklesham Beds.
