The parish, located on Harwood Street, was established in 1914 and primarily served Mexican immigrants. Bishop Thomas Tschoepe of Sacred Heart invited Our Lady of Guadalupe to merge with Sacred Heart, and by 1975, the Guadalupe church on Harwood closed following the churches' consolidation. On December 12, 1977, Sacred Heart Cathedral was renamed Cathedral Santuario de Guadalupe ? "the Cathedral Shrine of Our Lady of Guadalupe."[1] This reflects the large Spanish-speaking proportion of the congregation, so that the congregation now has masses and various programs in Spanish and English, as well as English classes.
