Melin Newydd Tynlon · Isle of Anglesey · Wales

Melin Newydd stands near Tynlon, on the former Bodorgan Estate, set back from the east side of a country road leading north from the B5109 between Glan-yr-afon and Trefor. Its name means New Mill and was used to distinguish the windmill from an existing nearby watermill. The two mills were used in conjunction, with the miller choosing the better source of power according to weather and water conditions.

The windmill was built in 1833 and is one of the last working windmills erected on Anglesey. The date is inscribed on a stone above the north doorway, together with the initials O J A F M, for Owen John Augustus Fuller Meyrick, owner of the Bodorgan Estate. The tower is circular and built of mortared rubble masonry, formerly rendered, with some render surviving. It has opposing ground-floor doorways, upper windows with rough voussoir cambered heads, and stands on a raised circular platform with a rubble revetment wall.

The mill remained in use into the early twentieth century. Sutton's Directory named Rowland Roberts as miller during the 1890s. He was followed by William Roberts, who worked the mill until the early 1920s. A severe storm then caused serious damage, forcing closure. The cap and sails were removed, the machinery was taken out, and the tower was given a corrugated-iron roof. It was later used as a cowhouse.

The tower was listed at Grade II in 1970 as a good example of an early to mid nineteenth-century windmill tower retaining its original planned form, openings, and character. In the twenty-first century it was converted from agricultural survival into holiday accommodation. Work began after purchase in 2006 and was completed in 2009. The converted windmill now forms part of Melin Newydd Cottages and retains the external identity of the historic tower within a modern holiday-let complex.
