Castell Trefadog

Castell Trefadog is a heavily overgrown ditched enclosure on a promontory site on the west coast of Anglesey. It is not possible to access the site directly, and in order to see it permission must be gained as the field is used for livestock. The site has suffered erosion from the sea, but LIDAR shows that the enclosure is roughly squarish, and there is evidence of a perimeter rampart around the enclosure.
