The campus's are also home to the motherhouse of the Sisters of Providence of Saint-Mary-of-the Woods, whose buildings date from the 19th and 20th Centuries. The Indianapolis architectural firm of D. A. Bohlen, Architect, and its successors, D. A. Bohlen and Son; Bohlen and Burns; and Bohlen, Meyer, Gibson and Associates, completed "more than sixty projects" for the Sisters of Providence, including all six of the historic buildings. More than twenty of the firm's projects, including Foley Hall (1860, 1897) at Saint Mary-of-the-Woods, are listed on the National Register of Historic Places. Foley Hall was demolished in 1989. Campus architects retained its pastoral setting, while a "French influence reminiscent of Georges-Eugène Haussmann" is visible in the "straight walkways and open views". The historic buildings on campus were representative of popular architectural styles at the time of their construction. From 1894 until the 1970s, three generations of the Joseph Bisch family supervised maintenance of the campus. Guerin Hall (1913) Anne Therese Guérin Hall, designed by Oscar D. Bohlen in a Renaissance Revival style, is named in honor of the foundress of the Sisters of Providence of Saint Mary-of-the-Woods. Construction for the four-story brick building began in 1911; it was dedicated on October 12, 1913. Guerin Hall was the college's first residence for students. Its lower floor contained offices, classrooms, and a chapel, while its upper floors offered semi-private rooms, a new trend in student housing at that time. The ornate front entrance features heavily carved Corinthian capitals on pilasters, made of Indiana limestone. Guerin Hall surrounds an open courtyard and a veranda extends across the front of the building. Conservatory of Music (1913) Saint Cecilia Conservatory of Music was designed by Oscar D. Bohlen and constructed between 1911 and 1913, the same time as Guerin Hall. The Conservatory is located "on the site of the second Saint Mary-of-the-Woods village church and cemetery." The three-story, Italian Renaissance Revival-style Conservatory was constructed of light brick and Bedford limestone. It has Ionic details and Beaux-Arts influences. The Conservatory was dedicated along with Guerin Hall on October 12, 1913, and contained music studios, practice rooms, classrooms, and offices. Cecilian Auditorium, which "seats up to 720 people on the main floor and balcony", provides a theatrical space that includes a proscenium stage and theatrical lighting.
