18th century? Circular. Sloping wall. Rubble part rendered. Roofless. Rectangular windows. Used as outbuilding. Shell only. <1>

Melin Llidiart is believed to be one of the oldest surviving windmills on Anglesey. Little is known
of the early history of the mill and a single surviving documentary reference was sourced. It is mentioned in the diaries of Squire Bulkeley of Brynddu that on the 24th October 1738 Llwydiath Mill began to grind the first corn. The site was identified as the mill at Llwydiarth Farm, Capel Coch by R. O Roberts (1958: 8).

On the first edition Ordnance Survey map of Anglesey dated 1889 (figure 11) Bryn Felin is shown as a corn mill and there are a number of associated outbuildings. In addition to the surviving main house there is a building between the house and the mill which is possibly a kiln or granary structure.

The mill was severely damaged in a storm during the late 1890's and lost the cap and sail. It was never replaced and the structure was used as an animal shelter. The loss of the mill cap and sail is evidenced in a 1910 photograph of Capel Coch (figure 13) and the 1920 Ordnance Survey Map (figure 14) which shows the mill as disused. (Jones & Rees 2012)
