Chantry is a term used to describe an ALTAR or chapel dedicated to the celebration of Mass. It is usually associated with a religious order, such as a monastery or convent, and is often found in churches and cathedrals. The word chantry comes from the Latin cantare, meaning 'to sing, ' and is related to the French chantier, meaning 'WORKSHOP.' Chantries were often used for private prayer and meditation, as well as for public worship.
