In 1965, at the urging of Bishop Charles E. Bennison Sr., a Diocesan Convention approved building the new Cathedral, and the next year Chicago-based architect Irving W. Colburn was hired.

At the entrance, the cathedral featured bas-reliefs executed by Leo Lentelli in 1922 for the facade of the Straus Building at the corner of Michigan Avenue and Jackson Boulevard in the City of Chicago from 1922 to 1952.

[2] The last dean of the cathedral was the very Reverend Cynthia L. Black, who also served as president of the Episcopal Women's Caucus from 1995–2000.

[3] The carillon was eventually bought by the Gordon Stuart Peek Foundation and donated to the University of Washington, where it sits on top of a ventilation shaft on Kane Hall as of 2020[update].

[4] The Cathedral has the distinction of appearing twice on Nicholas Hahn's list of “Ugliest Churches in the World,” both in its first incarnation and in its renovation as a mega-church.
