St. Pius X School was constructed in 1962. A new wing was built in 1967 to allow the building to support 560 students. The seven acre campus is located in Baltimore County just minutes south of Towson. The grounds afford the students ample physical education and play space on one full size athletic field, a large playground, and two blacktop lots. The use of the adjoining Baltimore County Athletic Fields allows for a generous use of space for field day activities, gym classes and special events.

The two story building consists of twenty-three classrooms, a library, a computer lab, a gymnasium/auditorium, a health suite, teacher's lounge, resource room and many individual offices. Ongoing renovations provide a safe and adequately equipped facility.
