The chapel, now dedicated to St
Mary and to fishermen, is older than the parish church, alongside which it
stands. It is thought to be on the site of an earlier church of Anglo-Saxon
date; the chapel originates from the 11th century. (Excavations have revealed remains of an earlier building) It survived the Reformation
which swept Jersey, and was used for a variety of secular purposes, befor being
restored as a building for prayer and worship in the early 20th century. Its
main feature are the frescoes, dating from the late 14th century, which were
discovered during this restoration. The most clear is the Annunciation scene on
the east wall.
