Description

Corn windmill, built in 1730 at Earsham Street and moved to its current location around 1823. The mill was damaged in a storm in October 1987. It features a roundhouse made of clay lump, which is plastered and tarred, topped with a boarded conical roof. Part of the timber-framed buck remains above the roundhouse. The roundhouse is circular and has a rectangular-plan buck, characteristic of an East Suffolk post mill. It is a two-storey roundhouse with a buck that was formerly three storeys high. The roundhouse has two boarded hatches with boarded doors below and a ladder leading to the buck, which was once turned by a six-bladed fantail that is now missing. Inside the roundhouse, there are brick piers and crosstrees on the bottom storey, a full-height stop-chamfered post with quarter bars to the buck, and two pairs of engine-driven millstones on a hursting, complete with tuns, horses, hoppers, and other equipment.

It experiences an average of 31 freeze-thaw cycles a year, fewer than 61% of listed buildings. Of these, 17 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.
