English: Built in 1951-1952 and internally finished in 1966, this Romanesque Revival-style building is now the Shrine of Saint Philippine Duchesne, and was originally intended to be a larger structure, with a nave to the south having never been completed, the location of which is still visible as a buff brick exterior on the south face of the building. The building features roman arched stained glass windows, decorative columns, an entrance portal with a decorative mosaic, and a gabled red terra cotta tile roof. The modernist interior of the church was designed in 1964 by William Schickel and Barbara and David Day, all from Cincinnati, the latter of whom are better-known for their drawn illustrations. The chapel houses a shrine and the remains of Rose Philippine Duchesne (1769-1952), a French woman who founded the school, the first Sacred Heart Academy in the Americas, and was known for her missionary work in the early-to-mid 19th Century, and was canonized as a saint in 1988. The building is a contributing structure in the Frenchtown Historic District, listed on the National Register of Historic Places in 1991. The building comprises the chapel of the Sacred Heart Academy, a Catholic school founded in 1818.
