Llynon Mill is an ancient windmill built in 1775 and is the last surviving windmill in Wales. The mill was restored by the Anglesey County Council in the 1980's, Llynon Mill is now under management by Richard Holt and his family. They have a wonderful shop that sells cakes of all kinds called Mônuts and have a great selection. You can go in the mill for a small cost. Don't forget to check out the ancient stones that are around the windmill itself.

Ffynnon y Wrach is virtually impossible to miss, a strange alien structure at the very side of the road beneath Holyhead Mountain as you ride up towards South Stack. An octagonal brick tower beneath a hemispherical rusted metal dome. Ffynnon y Wrach is generally translated as the Witches Well. The name dates back into antiquity the earliest date I have found of a written record being 1733; but there is no knowledge of the witch or witches to which its name might refer.
