[5][6] It served as a home for devotional exercises and Sunday Masses, and the site was entrusted to the care of the Sisters of St. Francis of Penance and Christian Charity, on August 28, 1927, and remained so until 1971.

[2][7][8] A Romanesque chapel with a capacity for 120 congregants dedicated to St. Therese, along with a 32-room dormitory for retreat participants and other buildings designed by Robert Krause, was constructed in 1931 and dedicated on the feast of St. Therese by Bishop Hartley.

[9][8] In 1949, Bishop Michael Ready of Columbus oversaw the addition of murals to the chapel including depictions of the Temptation of Christ, the prophet Elijah in the desert, and Ignatius of Loyola and Charles Borromeo, both patrons of the retreat movement, along with the apse painting of Pentecost as recounted in Acts 2.

[11] In 1998, 18 of the original 75 acres were split off to be developed into a senior assisted living facility run by the Carmelite Sisters for the Aged and Infirm.

[13] The same year, the grotto dedicated to Our Lady of Lourdes on the grounds of the facility was rebuilt and restored.
