Melin Rhosfawr Brynteg · Isle of Anglesey · Wales

Melin Rhosfawr stands beside the B5110 at the north-east end of Brynteg. It is a former tower corn windmill and one of the surviving full-height windmill towers on Anglesey. The tower was built in 1757 and is a three-storey circular structure of mortared rubble masonry, partly rendered, with a sloping wall, cambered ground-floor doorway, and upper window openings with voussoirs.

The mill was recorded in the 1841 tithe apportionment for the parish as owned by John Hughes Esq. Richard Owen was then listed as miller. Census returns of the same year recorded him living at the mill house with his wife, six children, and a miller's apprentice. By 1851 the mill had been taken over by Richard Owen's son Robert.

Melin Rhosfawr has a notable literary association. It appears as Mona Mill in George Borrow's Wild Wales, published in 1862, during Borrow's search for places connected with the Anglesey poet Goronwy Owen. Borrow met the then miller, John Jones, who invited him for a meal and accompanied him around the area to see Owen's house and the local church. John Jones continued to run the mill until 1877, after which his widow Martha took over and continued as miller until her death in 1889. William Jones then ran the mill for a further period.

The mill closed in 1910. Its sails and cap were taken down and the machinery was sold for scrap. Coflein notes that all three editions of the 25-inch Ordnance Survey map, from 1889, 1900, and 1920, show it as a working corn windmill, although the working life had ended by about 1910. Maps and a 1903 photograph show what appears to have been a discontinuous stone platform, interrupted by the opposed doors, used for access when adjusting the common sails. The tower is now roofless and the top few feet have been removed, but the remaining rubblestone structure survives in sound condition. It was listed at Grade II in 1970 as a substantially intact Anglesey windmill tower and for its association with Wild Wales.
