Primary Reference Number (PRN) : 11791 Trust : Gwynedd Community : Llanfaelog Unitary authority : Ynys Mon NGR : SH3456872554 Site Type (preferred type first) : POST MEDIEVAL CORN MILL Status : Listed Building II
Description : Ruinous watermill and windmill (burnt out circa 1970). 8 pairs of stones driven by either water or wind. 4 sails, breast-shot wheel, 3 floors, 4 wire machines. Combined wind/water mill circa 1826. <1>
Built c.1825 for the Bodorgan Estate. Late C19th OS maps show the mill with a mill pond to the E and mill race to the W of the mill. The mill sails are thought to have been removed in 1930, with operation continuing with water power until c.1937. The internal structure collapsed in 1973 due to fire damage (Brooks & Laws, 2005).
A water mill, which was converted into an unusual combined water and windmill in 1825, that is, a windmill which also housed an undershot water wheel in the base of the tower. The medieval mill was almost certainly on the site of the present mill, as a mill is shown there on Lewis Morris's estate map of 1726. (Davidson 2002, p.21)
