Today is the solemnity of the only Marian apparition to have occurred in the United States that has been approved by the Vatican.

The annual solemnity of Our Lady of Champion celebrated each 9 October marks the apparitions witnessed by Adele Brise, an immigrant from Belgium living in northern Wisconsin, in 1859.

In 2022, the Vatican gave its formal stamp of approval to the apparitions Brise witnessed, recognising the newly named National Shrine of Our Lady of Champion in Champion, Wisconsin, as an approved apparition site – currently the only one in the entire United States of America.
