the church's interior was decorated by John A. Mallin, who decorated many other churches in Illinois, with two years of planning and another two years to execute the project. St. Hyacinth's is also home to the masterworks of such renowned painters as Tadeusz Żukotyński and Mary Stanisia. Beginning in the mid-1990s, and taking almost a decade, the interior was renewed thoroughly, much of the mural work being performed by Conrad Schmitt Studios of Wisconsin. The stained glass windows have been identified as prepared by Meyer Co. of Munich, Germany, and some by the Zettler Co. of New York were installed in 1921.
