Melin Llynon (Llynnon Mill)
Restored 18th-century windmill near Llanddeusant, billed as the last working windmill in Wales, with replica Iron Age roundhouses, a woodland animal trail and Mr Holt's Mônuts doughnut shop.

Melin Llynon near Llanddeusant is a tower windmill built in 1775 and restored in 2024, which its owners describe as the last working windmill in Wales. Next to it stand two replica Iron Age roundhouses, built in 2007. The site is now run by the family behind Mr Holt’s chocolate.
What to see and do
Windmill tickets also cover the roundhouses and the Model Saffari, a woodland trail where life-size wild animal models hide among the trees, aimed especially at young children. Mônuts, the takeaway doughnut shop on site, also sells hot drinks, thick shakes, soft serve and a small selection of gluten-free or vegan cakes; it is not a sit-down café and doesn’t sell sandwiches.
Good to know
The windmill opens to the public between April and September, and the sails are not guaranteed to be turning on any given day. Mônuts and the site are open every day from 24 October to 1 November for October half term; the site opens mainly at weekends, bank holidays and school holidays, so check Mr Holt’s opening times page before you go. Dogs are welcome at the windmill. The steps inside the windmill are not suitable for disabled visitors.
