Halnaker Mill

Halnaker Mill was first mentioned in 1540 as belonging to the manor of "Halfnaked". It was built for the Duke of Richmond as the feudal mill of the Goodwood Estate. The surviving mill is thought to date from the 1740s and is known to have been standing c.1780. Halnaker Mill was working until struck by lightning in 1905, damaging the sails and windshaft. The derelict mill was restored in 1934 by Neve's, the Heathfield millwrights as a memorial to the wife of Sir William Bird. Further repair work was done in 1954 by E Hole and Sons, The Burgess Hill millwrights. The mill was again restored in 2004. The mill is owned by West Sussex County Council.

Halnaker Mill is a four-storey tower mill with a sixteen-sided beehive cap. The mill was originally hand-wound, and later fitted with a fantail, which was not replicated when the mill was restored. The four common sails were originally carried on a wooden windshaft, which was damaged by a 1905 lightning strike. A cast-iron windshaft and wooden brake wheel from a wind sawmill at Punnetts Town were fitted. The windshaft is cast in two pieces, bolted together, and is too short for Halnaker Mill. Neve's inserted a spacer to lengthen it. The mill worked two pairs of overdrift millstones.
