Ave, Regina Caelorum is a hymn in the Gregorian chant repertory of the Catholic Church and is usually sung to celebrate the Virgin Mary at the end of Compline.
We don't know who originally wrote the prayer but it is thought to date back to the 12th century.
It has been set to music by many composers, including Haydn.
