The cornerstone of Sts. Peter and Paul church is dated June 29, l844 making it the oldest church building in the city of Detroit.  It was completed and consecrated as Detroit's Catholic Cathedral  on June 29, l848. The builder of the church was Bishop Peter Paul Lefevere, who headed the Catholic diocese until l869. His body was buried in the building until l939.  His successor, Caspar Borgess, gave the title to the building to the Jesuit Order (Society of Jesus) in l877 as part of an agreement to start Detroit's first Catholic College, which became the University of Detroit-Mercy. The law school of the university still is adjacent to the church. In its 150 plus years of existence, the church has served a wide variety of Detroit's citizens, and is an active partner in the reconstruction of the downtown area.  The church is now totally owned and operated by the Jesuit Order in the Metro-Detroit area.

LOCATION:  The church is situated on East Jefferson Avenue, next to the University of Detroit-Mercy Law School, one-block West of I-375, and across the street from the Renaissance Center.
