Waltham Windmill

Waltham Windmill is a Grade II* tower windmill built in 1880 by John Saunderson of Louth. Since 1966, it has undergone restorations. The windmill features a tarred brick tower with a wooden cap and sails, and it has a tapered round shape with six storeys. The entrance includes a two-fold recessed board door, and there are original 20-pane iron casements in renewed wooden frames beneath segmental arches. The second floor has four windows, while the other floors have two windows each, with single windows on the third and fourth floors (the original two on these floors are now blocked). A corbelled cornice adorns the top of the tower. The wooden ogee cap has been renewed and includes a ball finial, a fantail, and six sails, of which two have been replaced and the rest restored.

Inside, the windmill contains a complete set of machinery, including two over-driven and two under-driven stones, with one of each being French burr and the other Derbyshire millstone grit. The main and subsidiary shafts and wheels are made of cast iron, with alternate cogged wheels in wood to prevent sparks. The original sack lift operates on a continuous chain, driven by a wallower, and the interior retains its original floor beams along with restored or renewed corn chutes, stairs, and floors. This windmill is notable as the last six-sailed mill built in Lincolnshire and is the only such mill currently in full working order. It is maintained and operated by the Waltham Windmill Preservation Society.
