Melin Wynt y Craig Llangefni · Isle of Anglesey · Wales

Melin Wynt y Craig stands in a prominent elevated position in the north-eastern part of Llangefni, on a rocky crag above the town. It is also known as Melin y Graig and Craig Mill. Its siting gave excellent exposure to the wind and made the tower a landmark visible from a wide surrounding area.

The mill was an early nineteenth-century wind-powered corn mill, thought to have been built in 1829. Local directory evidence places its construction between 1828 and 1833: Pigot's directory of 1828 listed only a watermill in Llangefni, while the next edition in 1833 mentioned Craig Mill, then being run by William Hughes. The mill stood on the Pencraig estate, owned by Richard Poole. In 1839 the estate was sold to Richard Griffith of Fitzwilliam Place, Dublin, later Sir Richard Griffith, 1st Baronet.

The 1843 tithe apportionment showed Richard Griffith as owner of the mill and surrounding Llangefni estate land. The mill itself was occupied by Rowland Owen and John Williams. Rowland Owen remained in charge until his death in 1876, assisted at times by other millers who occupied the mill residence. By 1871 William Williams had taken over day-to-day running of the mill and worked it through the 1870s and 1880s before emigrating to Manitoba in 1887. The final miller was William Jones, remembered locally by the nickname Angau Melinau, or death of mills, because he was also the last miller at two other Anglesey mills.

The mill closed in 1893. By the turn of the century it had fallen into poor repair, with the sails dismantled and the machinery removed. By the 1930s photographic records showed the tower as an empty shell. In 1914 the mill and Craig Fawr farm were sold to the Urban District Council of Llangefni. In the later twentieth century the tower became a local problem site before restoration work began in 1995. A modern cap was added and the tower was adapted to house mobile-phone transmitter equipment, with a mast on top. The equipment was removed in 2020 and the council began seeking a new use. Melin Wynt y Craig was listed at Grade II in 1952 as a substantially intact windmill tower and one of the surviving examples of Anglesey's former windmill landscape.
