Melin Llynon, Llanddeusant
windmill on Anglesey, Wales

Melin Llynon, or Llynon Mill, is a gristmill located on the outskirts of the village of Llanddeusant on the island of Anglesey. It is the only surviving working windmill in Wales.
Founding
The mill was built on land owned by the surgeon Herbert Jones for £529, 11s in 1775–1776 (equivalent to £100,000 in 2025). It is classified as a tower mill. The machinery is within a stone tower and the moving top, or cap cwch, turns so that the sails hwyliau catch the wind from any direction. The tower was 9.3 metres tall and with four floors. It was used to drive machines for grinding corn, oats and barley. The first miller, Thomas Jones (1756–1846), worked it until his death. The position of miller was passed down through the generations, eventually going to a cousin William Pritchard. By 1929, the mill was registered as disused and in use again.

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 11, 2026. The linked authority identifier is Q6812427. Authority coordinates are 53.338, -4.494. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1775, 1776, 2025 and 1756.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
