On April 27, 1890, the cornerstone for the new cathedral was laid. Gas pipe that was to be used for interior lighting was laid in February 1891. That same month lathing was applied and the walls and ceiling were plastered in April. The woodwork was completed by June. The frames for the windows were manufactured at a mill across the river in Rock Island, Illinois. The frame for the large window in the apse weighs 3½ tons. The windows were donated by individuals and groups. The new cathedral was finished in 1891, and it was dedicated on November 15 of that year.
