[2] Schulte designed two other Milwaukee churches in the same style: St. Mary's on North Broadway and Holy Trinity at Walker's Point.

[1] After forty years Schulte's original steeple was deemed unsafe and the section above the clock was replaced with a taller tower in 1893, which was designed by noted Milwaukee architects George Ferry & Alfred Clas.

Richard Perrin tells: "The nave and chancel areas were gutted, precious stained glass windows, mural paintings, as well as a valuable pipe organ, were completely destroyed.

The building was rededicated on February 9, 2002, following a controversial renovation project which consisted of some restoration work on the historic structure but also a radical remodeling of the interior.

Archbishop Rembert Weakland was the primary advocate of the renovation which he and supporters felt brought the cathedral into a more modern "post-conciliar" style.

[5] Among the most controversial elements of the renovation was the dismantling of the historic High Altar and Baldacchino in the apse which were replaced with organ pipes.

The sanctuary and altar was then moved forward into the nave and crowned with a fiberglass crucifix designed by Italian sculptors Arnaldo Pomodoro and Giuseppe Maraniell.
