After a 1901 fire that destroyed much of what was then called the "Catholic University of Oklahoma", the decision was made to move the high school and college to Shawnee, 35 miles (56 km) to the north.

A specialist in Tudor revival architecture, Klutho designed a massive five-story brick building to combine church, school and abbey in a single edifice, opening to 40 boys in the fall term of 1915.

From the main mass on either side extend four-story wings on raised basements, accented by projecting three-story oriel bays.

Timberlake Construction and Advanced Masonry, both of Oklahoma City, were charged with the task of rebuilding the turrets – this time with steel "bones" that could withstand an earthquake.

The brick was matched to the rest of the building, and the grotesques and shields that were part of the original gothic architecture were molded in the exact image of their predecessors.
