Clewer Park is the last remnant of the estate of the manor house Clewer Park dating back to the 15th century. Sir Daniel Gooch owned it from 1859 until his death in 1889. In 1923 it was thus described in the History of the County of Berkshire:
Clewer Park, the residence of Mrs. Mosscockle, is a large three-story stucco mansion, standing in its own grounds on the river bank just to the east of the Windsor race-course.
It was acquired by the Admiralty at the outbreak or World War II and housed Wrens as part of the President III based primarily at Dedworth Manor. The house was demolished in the 1940s.
An estate of 63 houses was built in the 1960s where the house had been, and the remaining land divided between allotments and the present-day Clewer Park, now a public open space run by the Royal Borough of Windsor and Maidenhead.
