Welcome to the
University of Saint Mary of the Lake!

The founder of our seminary, George Cardinal Mundelein, is also the namesake for the town in which we are located. We ask you to keep a sense of sacredness while you visit the grounds, and maintain an atmosphere conducive to prayer, study, retreats, peacefulness, and safety for not only our students but also for you, our guests. Unescorted visitors must be at least 18 years of age.

Groups of visitors are encouraged to contact us in advance at 847-566-8290.
