The campus also includes the historic 1905 church ("Old Saint Mary's") at the corner of Park Avenue and York Street, and Ste.

These two church buildings are listed on the National Register of Historic Places In February 1840, Count James Achille de Caradeuc, a French army engineer purchased over 400 acres of land about five miles east of Aiken,[2] near the present day community of Montmorenci.

[5][6] The 1905 church was built to replace the much smaller Ste Claire Chapel in response to a growing Catholic population.

The three large windows surmounting the north, south, and west facades are: North - the Blessed Virgin Mary, Help of Christians; South - St. John the Baptist, patron saint of the Diocese of Charleston; and West - Jesus Christ in Majesty.

The bells with their inscriptions: - Saint Anthony of Padua – note D-3 – 3,199lbs: “I will offer sacrifices with shouts of joy, singing and praising the Lord with music.”  Psalm 27:6.

The left side shrine of the 2015 parish church is dedicated to the Blessed Virgin Mary and features a nearly life-size bronze statue of the Madonna and Child by Gustave Doré.

This statue, which was cast in the 1880s was donated to St. Mary's parish in 1947 by Beatrice Kinney Lamantagne, another winter resident of Aiken.

Saint Joseph holds a staff topped with lilies in his left hand and an image of the facade of St. Peter's Basilica in his right.

These circular paintings within the architectural feature between the arches of the nave and sanctuary called a roundel depict different titles of the Virgin Mary, mostly from the Litany of Loreto.
