It is thought that Clewer and Dedworth were originally Saxon villages. They are certainly listed as manors in the Domesday Book of 1086, under the Saxon names of Clivore and Dideorde, when the populations are estimated to have been about 60 and 20 respectively.  Both manors were in the Berkshire Hundred of Ripplesmere.

Following the Norman Conquest in 1066, the ownership of Clivore had passed from Harold, Earl of Wessex to Ralf, son of Siegfried, whilst Dideorde had passed from Hugh the Chamberlain to Albert of Lotharingia.

About 1070, the high ground of Clivore was taken for the building of Windsor castle.  For many centuries the Crown paid rent to the manor of Clewer.

None of the pre - 12th century buildings of Dedworth or Clewer have survived, but at about the year 1100, the nave of St. Andrew's Church in Clewer was built.

Mill House at the end of Mill Lane in Clewer marks the site where a mill stood for over 800 years.  It is thought that there was probably a river landing point and a ferry crossing of the Thames nearby.

Did you know that many of the roads between Ruddlesway and Smiths Lane are named after 16th century Windsor Mayors? One of the best remembered, three times mayor Richard Gallys, was landlord of the Garter Inn, immortalised in 'The Merry Wives of Windsor'.  Testwood Road and Pierson Road are named after two of the Windsor Martyrs. In1543, in the reign of of Henry VIII, Anthony Pierson, Robert Testwood and Henry Filmer were found guilty of heresy and burned at the stake below the Castle.

Robert Testwood was a member of St. George's Chapel choir and Anthony Pierson was a preacher in Windsor. Their associate John Marbeck, organist at St. George's Chapel, was pardoned and lived to tell their story. His name lives on in Marbeck Close.

By the mid-1800s Dedworth was still a small settlement set 2 miles west of the growing town of Windsor. A map of 1856 shows that the major road pattern we have today was in place with Maidenhead Road and Dedworth Road linked by Roses Lane and Smiths Lane.  Clewer Hill Road linked Dedworth Green to Clewer Green. Wolf Lane was a track that ran up the hill to the St Leonard’s Mansion (which is now the site of Legoland).  There were a few houses stretched along the Dedworth Road at Dedworth Green plus a few larger properties but essentially Dedworth was an area of fields and farms on the lower land with forest up on St Leonard’s Hill.

When the decision to build All Saints Church was taken in 1861 the site was a field at the junction of Dedworth Road and Clewer Hill Road. The houses in Church Terrace were built in 1888.

Dedworth, as we know it today, developed westwards from Clewer starting in the 1930s and 40s with housing at Dedworth Drive and St Andrews Crescent. In the l950s with the housing at Perrycroft, Priors Road and the ‘prefabs’ at Foster Avenue (replaced in the early 1970s). In the 1960s the ‘Laing’ estate (to the west of Smiths Lane) provided nearly one thousand houses and flats that extend over a large area which had mostly been fields and open countryside. Three roads on this estate were named after Protestant Martyrs, Robert Testwood, Henry Filmer and Anthony Pierson, burned at Windsor Castle in 1544.  A development on fields and woodland in the late 1960s and early 1970s provided housing in the White Horse Road and Hemwood Road areas. Also in the 1970s the Broom Farm army estate was developed.   Since this time little new housing has been built in Dedworth

The Medieval Manors of Dedworth

An irregular quadrangular moat in Wolf Lane is all that remains of the manor house of Dedworth Loring. It was owned by the De Loring family from the time of Peter De Loring in the early 13th century. The other manor in the area was Dedworth Maunsell, which may have been located to the north where a large medieval hearth has been uncovered in the aptly named Knight’s Close

The origins of Dedworth

The town of Windsor in Berkshire, England, home of the famous castle, has grown to encompass three Saxon villages, these being:

• Clewer
• Dedworth
• Losfield (It is now believed that Losfield was actually part of St Leonards)

Of the four only Clewer and Dedworth survive as defined areas of Windsor. Losfield is remembered by the street name Losfield Road

Located within Clewer is Windsor Castle, the site was rented by the Crown for the princely sum of 12 shillings a year for 500 years. This was paid to the lord of Clewer Manor.

Where does the name come from?

The Name Dedworth comes from two words "Dydda" - a mans name, and
