Site overview
Newnham Windmill stands at Newnham, south of Daventry. It is recorded as a surviving tower mill converted to an observation tower. The mill appears in Northamptonshire windmill listings as a tower mill at the supplied coordinates, and older industrial archaeology references record Newnham Windmill on historic mapping, later also marked as Old Windmill.
The available evidence identifies a surviving tower-mill structure and its later conversion, but provides limited detail on the mill's construction, machinery, named operators or exact closure date. The site is therefore best understood as a former wind-powered corn mill whose tower has survived through reuse, with its present character defined by conversion rather than restored milling function.

History
Newnham Windmill stands in the village of Newnham, south of Daventry. It is recorded in modern windmill inventories as a surviving tower mill converted to an observation tower. Earlier industrial archaeology references place Newnham Windmill on the first-edition Ordnance Survey mapping and later on the 1912 one-inch mapping as Old Windmill.
These records confirm the site as a recognised historic windmill location with an extant tower, but they do not provide a full account of the working machinery, sail arrangement, millwright, ownership sequence or final working date. The present form is one of reuse: the mill survives not as an operating corn mill but as a converted tower structure. The evidence supports a cautious account centred on location, former tower-mill function and later conversion.
Its survival as an observation tower preserves the vertical shell of the historic mill while changing its use and removing the working milling character.
