Chapel of St. Francis de Sales
The heart of Mount de Sales Academy is its chapel. Located on the second floor in the center of the main building, it is the oldest active house of Catholic worship in Baltimore County. Stained glass windows crafted in Chartres, France are prominent in the sanctuary, and include scenes from the life of the Blessed Mother, as well as the academy's official seal. An 1884 Jardine pipe organ in the choir loft is still in regular use and was the focal point of the 1991 meeting of the National Organ Historical Society.

Daily Mass offers students, faculty, and staff the opportunity to worship together in the presence of Christ. Students also participate in the celebration of Mass on First Fridays and various special occasions.
