Originally located in Delvin, Ohio two miles east of North Star

St. Louis Church was originally built in 1914, but an extensive expansion and renovation project led to the church's rededication in 2000. The expansion included an enlarged sanctuary, exposed trusses reminiscent of the first church building and two stained glass windows from the now closed St. Pius Church in Cincinnati. The Eucharistic chapel for private prayer resides behind the wrought iron gate in the sanctuary. The church was added to the National Register of Historic Places in 1979.
