This mill is unique on Anglesey in that it had both wind and water powered machinery in the same building. The water wheel in the lowest floor and the sails on top both connected to a central shaft that ran the millstones. The miller could engage and disengage one of a pair of clutches to select which would drive the stones. This system meant that the sails rotated in a clockwise direction. The mill was built in 1825. It operated under this dual power system until 1930 when the sails were removed. It continued to be worked by water power for several more years. In 1973 a fire, started by children gutted the tower, burning out all the floors and allowing all of the  machinery to collapse into the base of the mill One pair of the millstones landing on the wheel breaking the shroud.

Very little accurate information existed about the mill. The drawing has been compiled from information and  photographs held in the Archives of the Royal Commission on the Ancient and Historical Monuments of Wales (RCAHMW) and the 400+ photographs in their on line database Coflein. Much the internal layout is based on the survey carried out by Rex Wailes in 1928 and his report in the articleprinted  in the Miller in 1929, also the extensive studies of the mills on the Island by Mr John Crompton. I would like to personally thank John for the time he spent with me studying the photographs showing the remains of burnt out floor timbers still in place within the tower after the fire to decide where stair cases and the sack hoist etc. were located his other photographs and the many other details he helped me to solve
