About
Melin Llynon at Llanddeusant in northwest Anglesey is the only working windmill in Wales, restored in 1986 from a derelict shell and now grinding flour with its original stone mechanism when the wind allows — producing wholemeal flour for sale on-site at a rate that remains unchanged from its 1776 construction date. What makes Llanddeusant genuinely unusual is the combination of the working windmill with a reconstructed Iron Age roundhouse village on the same site, built to original specifications on the evidence of cropmarks nearby, giving families a rare opportunity to compare medieval technology with Bronze Age and Iron Age building methods in the same field. The windmill grinds on windy days only, so call ahead if you specifically want to see it in motion; the roundhouses and the wooded setting on the Alaw valley's edge are worth the visit regardless.

Frequently asked questions
Is the mill always working?
No — the mill grinds only when there is sufficient wind to turn the sails safely. Call ahead if you specifically want to see it in operation. The site is worth visiting regardless for the roundhouses.
Can we buy the flour?
Yes — wholemeal flour ground on-site is typically sold at the mill when it is in operation. It is genuinely produced by the mill rather than a commercial product dressed up for the gift shop.
What are the Iron Age roundhouses?
A cluster of full-scale reconstructed roundhouses built using Iron Age techniques and materials, based on cropmark evidence from the surrounding valley. Families can enter and explore them, giving an immediate sense of scale and construction that photographs of archaeological sites cannot provide.
