Garboldisham Windmill

Garboldisham Windmill is a post mill dating from around 1780, constructed of brick and timber. It features a circular brick roundhouse topped with a conical timber roof. There are doors on the east and west sides. The buck, which is the part of the mill that houses the sails, is weatherboarded and has a gabled roof covered with felt, similar to the roundhouse. A scissor-braced ladder staircase leads to the first-floor door of the three-storey superstructure. Each lateral face of the buck has three blind windows.

Inside the roundhouse, the typical layout includes four brick piers that support cross trees, and four quarter bars that brace the main post, which descends through the roof. The main post extends into the buck and is stopped at the crown-tree. The upper storey retains the wind shaft, wallower, and drive shaft, which drops down to a great spur wheel that engages with the stone nuts of two underdriven pairs of stones. Notably, the sails and tiller beam are missing.
