Description

This is a windmill tower built in the late 18th century to early 19th century. The walls are made of flint measuring 650mm thick, with brick lacing in three and four courses and some areas rendered. The tower has a truncated conical shape and originally had four floors, which have now been removed. There are opposing doors on the north and south sides, and each floor has two windows set diagonally above the ground floor. The structure features a timber kerb.

Inside, the interior has been gutted, but there are remnants of a cast iron octagonal windshaft with canisters and a tail bearing, a six-armed cross for the fantail, a chair for the head brass, and various shackles. Additionally, there is a runner and the base of a pair of French burrs, along with decayed remains of timber shears. It is noted that the machinery was reportedly moved to this site from Middle Wallop in Hampshire.

Local climate

Windmill receives an average of 780 mm of rain a year. This makes it drier than 60% of listed buildings in the UK. Its exposure to wind-driven rain is greater than that of 60% of listed buildings.

It experiences an average of 30 freeze-thaw cycles a year, fewer than 63% of listed buildings. Of these, 12 follow at least 1 mm of rain in the preceding 48 hours. Average temperatures at this location have risen by 0.3°C per decade since 1991.

Averages for 1991–2020; temperature trend 1991–2025. Figures describe the wider area (a grid cell of roughly 10 km), not the individual site. Contains modified Copernicus Climate Change Service information 2026.
