Each of the six buildings that comprise the campus of Saint Peter's Prep possesses a unique history, and together they provide students, faculty and staff with a facility that wonderfully combines tradition and technology. The recent "Keys to the Future" and "carpe Diem" campaigns have funded extensive renovations and modernization across the campus, resulting in a physical plant that remains true to its architectural roots while anticipating future growth.

Shalloe Hall, the original school building, was built in the 1870s as Saint Peter's College and High School. Today it houses our non-academic administrative offices and the Chapel of the Madonna.

The Humanities Building (previously known as the Science, Freshman, and English Building), was constructed in the late 1880s as the Academy of Saint Aloysius, an all-girls' school administered by the Sisters of Charity. This magnificent, four-story structure received a multi-million dollar facelift in 1995, which, most notably, included a floor-to-ceiling renovation of its Siperstein Library and the installation of a CD-ROM computer center for research and word processing on the first floor. The lower level houses our expanded physical education facilities, including a new weight room, shower room and locker area. The upper three floors are devoted to classrooms and a newly expanded art studio. Mulry Hall, at the corner of Grand & Warren streets, was built next. It originally was the Saint Peter's Club, a Jersey City social club, until Prep took possession of it around the turn of the century and transformed it into a classroom facility. Today, it houses administrative offices, student counselors' offices, classrooms and the College Placement Center.

Hogan and Burke Halls contain most of the classrooms on the West Campus, with Hogan featuring the Link Computer Center and the Student Publications Center, and Burke containing the science labs, the new practice facility for the band and other music students, and the student cafeteria. The Memorial Gymnasium on York Street hosts all physical education classes, indoor intramurals, and home basketball, wrestling and volleyball contests. In the summer of 1995, this facility received an extensive renovation, which included a refurbished hardwood court, new lighting, wall padding, a modernization of the women's bathroom, and new game backboards, scoreboard and sound system.

Recent additions to the campus include the James F. Keenan, S.J., athletic field, and the Warren Street Plaza. In addition, in 2005, Saint Peter's Prep purchased Saint Peter's Grammar School, Saint Peter's Church and Shalloe Hall, and a comprehensive Master Plan is currently underway to determine the best use of these tremendous new facilities.
