The windmill in West Street, Dunstable, was built in 1839 for local landowner Richard Gutteridge.
Dunstable Tower Mill is a large tower mill of Caddington Grey Brick, 28ft diameter at the base with 3ft 6ins walls at the base and 2ft walls at the curb. The tower is unusual in that the first two floors are built vertically, the taper starting at second-floor level. The mill is 58ft high to the top of the cap, and contains five storeys.
The sails were removed in 1908 after the mill owner discovered that it was more reliable to grind corn using steam power.
This all ceased just before the Second World War, when the building was used as an observation post by the Home Guard.
It became the headquarters of Dunstable Sea Cadets in 1948. Admiral Sir Lionel Preston, who moved to live in Dunstable (in High Street North) in 1935, had been instrumental in forming a Sea Cadets unit as part of the Pioneer Boys Club in 1942.
The mill was Listed at Grade II on 24th October 1951. https://historicengland.org.uk/listing/the-list/list-entry/1146443
