The main campus was located in New Rochelle, a
Westchester County, New York, city about north of
Manhattan. In 1896, the college's founder, Mother Irene Gill, OSU, traveled to New Rochelle to explore the possibility of establishing a seminary there for young women. During this trip, she came across
Leland Castle, an 1850s
Gothic Revival structure and former vacation home of wealthy New York hotelier Simeon Leland. The castle was purchased in 1897 and became the first structure of the college. It has since been placed on the
National Register of Historic Places. The castle was part of the campus quadrangle and housed the "Castle Gallery". The campus consisted of 20 main buildings, including a $28M athletic, recreational, and educational complex called the Wellness Center (completed in 2008), which featured an
NCAA competition-sized swimming pool, basketball court, fitness center, indoor running track,
yoga studio, roof garden and meditation garden, and volleyball court; it also had the Mooney Center with computer and photography labs, and TV production studio; the 200,000-volume
Mother Irene Gill Memorial Library; the Student Campus Center; the Rogick Life Sciences Building with many laboratories; four
residence halls; and the Learning Resource Center for Nursing. Gill_Memorial_Library_1.jpg|Gill Memorial Library Gill Memorial Library 2.jpg|Gill Memorial Library Gill4.jpg|Campus == Athletics ==
