Maria Stein Convent
Also known as: Maria Stein Shrine; Shrine of the Holy Relics

Why it's listed
Maria Stein Convent, in Mercer County, Ohio, is a religious community founded in 1846 by the Fathers and Sisters of the Precious Blood, a missionary group from Germany and Switzerland. Its buildings include a brick residence of 1848, St. Joseph's Building, a gatehouse of 1849, a timber hog barn dated to 1845, and farm buildings from about 1890 to 1910. The heart of the complex is the Gothic revival convent with its Adoration Chapel and Relic Chapel of 1890, built of local brick with sheet-metal ornament and stained glass. A novitiate wing followed in 1892. The Relic Chapel houses relics of the saints brought from Europe and delivered to the convent in 1872. The convent was once the congregation's motherhouse. The nomination values it above all for continuity: a working community, supported by about 205 acres of farmland, that has carried on in much the same buildings and manner since its founding.
Significance in brief: The nomination argues the convent is significant chiefly because it has survived, in continuous operation since 1846, when most communal establishments fail. It became the most important American effort of the Precious Blood fathers and sisters, especially after receiving the relics of the saints in 1872. It remains a working community in largely the same buildings and way of life as at its founding.

What listing means for this property
Religious properties are listed for their architectural or historical significance, not their religious use. Listing is honorary and does not restrict the congregation's use of the building. The federal rehabilitation credit is generally unavailable unless part of the building is income-producing; some state programmes and preservation grants do cover religious buildings. Federal funding or permits trigger Section 106 review.
