It is also known as the O'Connor Church Complex. The main building is the church (1904–05), which is brick and soaring and Romanesque Revival in style. There is also a rectory (1929–30), a plain parish hall (1954–55), a cemetery, and surrounding windbreaks and other land.
The land was purchased in 1879 by the Irish Catholic Colonization Association of the U.S. which was organized in part "to aid the social, economic, and religious conditions of the Irish-American urban poor by assisting their relocation from eastern cities to farms in Minnesota and Nebraska." In total 25,695.9 acres (103.988 km2) in the area was purchased from the Burlington and Missouri Railroad, and townsites of O'Connor and Spalding were opened in 1880.[2]
