High Quality Content by WIKIPEDIA articles! St Mary`s Church, Rhodogeidio is a small medieval church, dating from the 15th century, near Llannerch-y-medd, in Anglesey, north Wales. It served as a chapel of ease to another church in the area, St Ceidio`s. Some restoration work was carried out in the 19th century, but St Mary`s has since fallen into disuse and is now largely in ruins.
