The site for the building of the Cathedral church was selected by Bishop John Carroll. It was purchased in 1905 through a generous contribution made by Thomas Cruse. Mr. A. O. Von Herbulis of Washington, D.C. was commissioned to be the architect. Mr. Von Herbulis was trained abroad and was chosen because of his extensive knowledge of the Cathedrals of Europe.
