Site overview
Seaton post mill was a wind-powered corn mill in Rutland, recorded at the supplied coordinates near Seaton. The mill was a post mill, not a tower mill, and formed part of a milling landscape in which wind and water power were used close together. The post mill was moved down the hill to stand beside Seaton watermill, allowing one miller to manage both sources of power.
Photographic evidence places the post mill beside the watermill after the construction of Harringworth Viaduct in 1878. The mill is also associated with the Royce family. The working history is only partly documented in the sources consulted.
The body of the post mill survived in later use as a barn until the 1980s, when it was disposed of. The present record therefore represents the site of the former mill rather than a surviving standing windmill.

History
Seaton had a post mill used as a wind-powered corn mill. Its recorded location is at Seaton in Rutland, close to the supplied coordinates, and not at Uppingham. The mill was part of a local arrangement in which a windmill and watermill stood near one another.
The post mill was moved down the hill to stand alongside Seaton watermill, so that the same miller could use both installations and continue milling when one source of power was less useful. A historic photograph shows the post mill beside Seaton Water Mill with Harringworth Viaduct in the background. Since the viaduct was built in 1878, the photograph must post-date that year.
The mill is also identified as the home of the Royce family, connected with Henry Royce's childhood. The surviving record does not provide a full working chronology, machinery inventory, or final date of wind-powered operation. The mill body survived after milling as a barn, but it was disposed of in the 1980s.
No standing mill structure is identified at the site in the sources consulted.
