Llanbadrig is a parish in the cwmwd of Talybolion, on the island of Anglesey, north Wales. The parish includes the township of Clygyrog and the little port of Cemaes (pronounced "Kem-eyes"). The region has extensive quarries of limestone and marble.
The Welsh name Llanbadrig means "Church of Saint Patrick" and there is indeed a Church of St. Patrick on the coast near Cemaes. It is said to have been founded in 440CE by St Patrick himself. Local legend states that Patrick was shipwrecked on the small nearby island of Ynys Badrig (Patrick's Isle, also known as Middle Mouse), which can be seen from the stile in the churchyard wall.
