There has been a manor in Halton since the Norman conquest, when it belonged to the Archbishop of Canterbury. However Thomas Cranmer sold the manor to Henry Bradshaw, Chancellor of the Exchequer in the mid Sixteenth century. After remaining in the Bradshaw family for some considerable time it was sold to Sir Francis Dashwood in 1720, and was then held in the Dashwood family for almost 150 years.
In the late Nineteenth century the manor was sold once again to the great Rothschild banking family, who were looking for a moderate house in the area where they could host parties and soirees. The house was completely remodelled by them into the grand mansion that it is today.
In the early Twentieth century Halton was bequeathed along with Green Park in Aston Clinton to the local authority, with the provision that the land and building be used for educational purposes. Green Park was thus turned into a school, and Halton was turned into an RAF training base, which is its current use.
