Diocese of Winona-Rochester

The Diocese of Winona-Rochester was established in 1889 and covers 20 counties across the bluff country and river valleys of southeastern Minnesota. Its 103 parishes are anchored by two cathedrals — the Cathedral of the Sacred Heart in Winona and the Co-Cathedral of St. John the Evangelist in Rochester. Saint Mary's University of Minnesota and the Immaculate Heart of Mary Seminary, both in Winona, have made the diocese a center of Catholic education in the Upper Midwest for well over a century.
