Llanarmon was located on several drovers' roads and owed much of its prosperity to the cattle which passed through on their way from Anglesey to the markets of England. In the nineteenth century it was one of the few places in north Wales where wheat was grown, through heavy treatment of the fields with lime, which also helped to create lush pasture for the drovers' cattle. The local limestone quarries provided employment after the droving trade died out towards the end of the 19th century.
