The USML grounds are open to the public from 12 p.m. to 5 p.m. daily. Guests must enter via the Route 45 entrance and park in the Purple Lot. Masks are required at all times. For the safety of our community, all buildings will be closed and restrooms unavailable due to COVID-19 restrictions. 

We welcome people to visit USML/Mundelein Seminary.  While these are private grounds, they are open to visitors between 9 AM to 5 PM daily.   In order to keep a sense of sacredness on the grounds, and keep an atmosphere conducive to prayer, study, retreats, peacefulness, and safety for our students and guests, we have a number of rules which must be observed.  These are listed generally on signage around the campus and on our visitors page.  Above all, visitors must follow the directions of Security Officers, or USML Administrators when they are present on the campus.  Some activities which are open to our students, faculty, and Conference Center guests, are also occasionally granted by individual permits to our visitors when they are requested in advance. More information on these activities can be obtained by contacting Dianne at dgiovannetti@usml.edu or calling 847-970-4801.
