The school was built in 1920-21 to serve the children of Roundup's Catholic immigrant community.

Coal production, an oil boom, and homesteading all drove economic and population growth in Roundup during the 1910s, and many of the city's new residents were European immigrants.

The city's newly established Catholic community built the school toward the end of Roundup's building boom.

Architect John H. Grant, who served as the city's only resident architect, designed the two-story brick building.
