Located in Waterloo, Illinois, Gibault Catholic High School serves the Diocese of Belleville and is only 20 minutes from south St. Louis County. Our 40-acre campus is continually being updated to meet the needs of our students.
Campus facilities include a gymnasium, weight room, renovated science labs, an Innovation Center and STEM room, and a library. There is a chapel on site for small Masses, prayer services, or individual reflection. Our most unique features are our beautifully maintained patio areas, which students may use as outdoor study spaces.
