Mills on the Air - Thaxted
GB0TWM John Webb's Windmill - 8th and 9th May 2021
The windmill was built in 1804 for John Webb, a local farmer and landowner, to satisfy the increasing demand for flour both locally and in London.cIt was constructed using local materials, with timber from two local farms and bricks made at a nearby location in the Chelmer Valley also owned by John Webb.
The mill was always worked by millers named Lowe or John Webb, thus gaining its names. The mill was last worked commercially in 1910. The mill was disused for over twenty years until the Thaxted Civic Trust carried out essential repairs and made the structure waterproof. The lower floors were used as a scout hut. The mill passed into the ownership of Thaxted Parish Council in the 1950s. The Thaxted Society, formed in 1964, has been instrumental in the restoration of the mill to full working order
