The present Gothic Revival structure was designed by Egan and Prindeville of Chicago and completed in 1906.

[1] Andrew Carnegie provided the cathedral's first pipe organ, originally a circa 1895 W. W. Kimball, which served into the 1950s.

Under organist and choirmaster Paul Koch's leadership, the cathedral contracted with Aeolian-Skinner to build a new large four-manual organ.

Named "one of the monument organs of the continent", it was completed in 1962, and has undergone several major refurbishment projects since.
