Parish Identity & Patron Saint
St. Leo the Great Catholic Church in Tyndall takes its name from Pope St. Leo I (440–461 AD), one of only a handful of popes honored as a Doctor of the Church. He is famed for his Tome of Leo, which defined the two natures of Christ, and for personally meeting Attila the Hun to plead for Rome. The parish's feast day is November 10. As a country parish in the Diocese of Sioux Falls, St. Leo carries this grand papal patron in the small setting of a Bon Homme County farming town.

History & Founding (1889)
Founded in 1889, St. Leo was established to serve the Catholic families — many of Czech and Bohemian origin — settling the farmland around Tyndall in southeastern South Dakota. The parish grew alongside neighboring St. Wenceslaus in Tabor (whose 1898 red-brick church is on the National Register of Historic Places as part of the 'Czech Folk Architecture of Southeastern South Dakota' thematic nomination). Together, these two Czech-country parishes form a small cluster within the Diocese of Sioux Falls, sharing pastoral care and the rhythms of rural Catholic life for more than a century.
- Founded: 1889
- Part of the Czech-Bohemian Catholic settlement of southeastern South Dakota
- Sister parish in shared ministry: St. Wenceslaus, Tabor
