The Welsh name Llanbadrig means “Church of St Patrick” and the church founded in 441AD has a direct link to the patron saint of Ireland. The then Bishop Patrick was sent by Pope Celestine to Ireland to convert the Irish to Christianity during the 5th century.
Patrick was shipwrecked on Tnys Badrig (Patrick’s Island also known as Middle Mouse) which can be seen from the stile at the churchyard wall. He crossed to Anglesey and found refuge in Ogof Badrig (Patrick’s Cave). The cave is situated below the churchyard and has a freshwater well Ffynon Badrig (Patrick’s Well). The freshwater allowed Patrick to recover and he founded the church as thanks to God.
