Academy of Our Lady and Spalding Institute were Catholic high schools across the street from each other near downtown Peoria, Illinois. AOL, a girls' school, traced its lineagle back to 1863; SI, the boys' school, was founded in 1899. They merged into one co-educational school, Academy of Our Lady/Spalding Institute in 1973.[1] AOL/SI (also known as Academy/Spalding) was merged into Bergan High School to form Peoria Notre Dame High School in 1988, and the campus was closed at the end of the 1988–1989 school year.
Buildings on the campus are contributing properties of the North Side Historic District.
