Explore Our Campus

From classrooms that support innovative learning to top-tier athletic facilities, our beautiful 360-acre campus in St. Louis county provides outstanding educational and character-building opportunities, often surpassing those available at comparable schools.

Students take full advantage of our 100+ acres of diverse habitats, which provide hands-on experiential learning opportunities with a focus on sustainability throughout the year. Even our fiercest athletic rivals love to compete on our campus in our Simon Athletic Complex and on our sports fields, track, and cross-country courses. 

From academics to athletics, from the arts to the dorms, Principia School's campus is an ideal place to test theories, conquer limitations, enjoy quiet time, and have fun with friends.
