Saint Martin’s has come a long way from the all-male school it once was—with only one building that housed the classrooms, dorms, library, cafeteria, and monastery. The main campus in Lacey sits on 380 acres surrounded by trees, trails, and even wildlife. There are currently four academic buildings (with a new School of Engineering building set to open in 2013), one library, a recreation center, one student union building, four residence halls, and a church. Saint Martin’s is the only Benedictine university west of the Rockies. The campus features a functioning monastery with more than 30 monks following the rule of the Benedictine Order. Next to it is the Abbey Church, which features an annual concert series called "Abbey Church Events."
Old Main is the University’s primary building used for classrooms, administrative offices, student services offices, science labs, the bookstore, and dining hall. In front of the building is the most recognized landmark on campus: the Grand Staircase. Students fondly call it the "Jesus Stairs" because of the statue of Christ at the top. Students tend to avoid climbing this because of the seemingly endless number of stairs. During the past decade, the school has actively been updating and adding to its facilities, from the O’Grady Library in 2001 to renovations to the Trautman Student Union Building (TUB) in 2010.
