Site overview
The supplied coordinates correspond to Key's Mill on Halvergate Marshes. The site is recorded as a tower drainage mill at grid reference TG 462 085. Online source coverage is limited, but the mill is consistently listed among the surviving drainage windmills of the Halvergate Marshes.
It should be distinguished from Halvergate village corn tower mill, from High's Mill, Mutton's Mill and Six Mile House Mill, all of which have separate names and grid references. The consulted sources identify the site as a tower mill used for drainage rather than corn grinding. No construction date, detailed machinery description, keeper chronology, closure date, restoration history or current condition beyond survival as a recorded tower site has been identified in the consulted sources.

Key's Mill is identified at the supplied coordinate position on Halvergate Marshes and is listed at grid reference TG 462 085. It forms part of the dense group of drainage windmill remains in the marshland between the Bure and Yare systems. The mill is recorded as a tower mill and as a drainage mill, but the consulted online sources provide only limited detail for this particular site.
The record distinguishes it from nearby and better documented Halvergate Marshes mills: High's Mill at TG 457 072, Mutton's Mill at TG 441 063, Six Mile House Mill at TG 461 098, and the Halvergate village corn tower mill at TG 416 059. No reliable construction date, dimensions, sail arrangement, scoop-wheel detail, ownership sequence or operational chronology was found during the consulted searches. The site is therefore recorded here on the basis of its positive identification as Key's Mill, a tower drainage mill on Halvergate Marshes.
