History and amenities


Llancayo Mill is situated in fields visible from the road. It was built around 1813[1] and destroyed by fire by about 1830.[2] The local story is that the miller left the mill gears engaged when he went to market, and when the wind changed direction the mechanism overheated, igniting the surrounding timber.[3][4] A Monmouthshire poet, Myfanwy Haycock, wrote a poem about the now disused windmill. It has now been fully restored, with working sails, for use as a "luxury retreat".[5]

The River Usk flows close by.
