St. Lawrence Seminary High School
St. Lawrence Seminary High School is located on 150+ acres in the rolling hills of central Wisconsin.
The center of the campus is located atop a prominent "Hill" that serves as part of our challenging cross-country course.
Eleven buildings fill the "Hill", from the traditional main building, Laurentianum, where the original St. Lawrence College met, to the beautiful, modern Chapel. These buildings hold everything the students need for daily life, including, but not limited to the Chapel, classrooms, computer lab, dorms, a gym, racquetball courts, a fitness center, a bowling alley, a store, the library, the dining hall, an auditorium and many other facilities.
Along and below the hill are two soccer fields, five tennis courts, a toboggan run and room for all kinds of "pick-up" games.
