Martyr and miracle worker...here is her shrine in Italy.
Note: Philomena was never officially declared a Saint. Her feast day was removed from the universal Roman Calendar in 1961 because of doubts about the historical accuracy of her life story, stemming from a lack of early documentation and conflicting archeological findings, though popular devotion and miracles attributed to her remain strong and officially permitted by the Church.
The Vatican's action was to align calendars with stricter historical verification, not to declare her non-existent, and she is still venerated as a powerful intercessor, especially by St. John Vianney and many Catholics.
The action wasn't an official declaration that she never existed or wasn't a saint, but a clarification of her liturgical status due to insufficient documentation.
The Holy See has not suppressed devotion to her; many miracles are still attributed to her intercession, and she remains a popular saint, particularly in places like Mugnano, Italy, where her relics are.
In essence, while her specific historical life story remains legend, the Church acknowledges the fervent faith and powerful intercession associated with the name "Philomena," allowing her cult to continue.
